If there are any differences in translation version of this document formal version takes priority Application example ROHM cannot provide adequate confirmation of patents. Therefore do not employ any method in which parasitic diodes can operate such as applying a voltage to an input pin that is lower than the P substrate GND.

When used in sealed area, confirm the actual ambient temperature. However, semiconductor products can fail or malfunction at a certain rate. Not connected 4 N. The following are examples of safety measures: High output voltage accuracy: These regulators are therefore ideal for applications requiring a direct connection to the battery and a low current consumption.

Includes switch Integrated overcurrent protection to protect the IC from damage caused by output short-circuiting. Should you intend to use this product with equipment or devices which require an extremely high level of reliability and the malfunction of which would directly endanger human life such as medical instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers and other safety devicesplease be sure to consult with our sales representative in advance.

For example, in case a resistor and a transistor are connected to the pins as shown in the figure below then: However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit.

If you intend to use our Products under any special or extraordinary environments or conditions as exemplified belowyour independent verification and confirmation of product performance, reliability, etc, prior to use, must be necessary: Therefore, when actually using the chip, ensure that the generated heat does not exceed the Pd rating. Only includes enable input Figure 8. Therefore, if any special mode is being considered with values expected to exceed the absolute maximum ratings, implementing physical safety measures, such as adding fuses, should be considered.

ROHM shall not be in any way responsible or liable for any damages, expenses or losses incurred by you or third parties resulting from inaccuracy or errors of or concerning such information.


Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage. Documents Flashcards Grammar checker.

Please take proper caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be applied to Products. It is strongly recommended to confirm solderability before using Products of which storage time is exceeding the recommended storage time period.

The amount of heat generated depends on the voltage difference across the input and output, load current, and bias current. Similarly, care must be taken to avoid wiring pattern fluctuations in any connected external component GND. ROHM shall not be in any way responsible or liable for any damages, expenses or losses incurred by you or third parties arising from the use of such information. Furthermore, these ICs also feature overcurrent protection to protect the device from damage caused by short-circuiting and an integrated thermal shutdown to protect the device from overheating at overload conditions.

This protection circuit is effective in preventing damage due to sudden and unexpected incidents. Also, make sure to turn off the power supply when connecting and disconnecting the inspection equipment.

In this event it also becomes impossible to determine the cause of the damage e.

Also, shorts caused by dust entering between the output, input and GND pin may result in damaging the IC. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the Pd rating.

After the Tj falls below daasheet TSD threshold the circuits are automatically restored to normal operation.

On the reverse side of the package this product has an exposed heat pad for improving the heat dissipation. Although the actual application might be the cause of the transients, the IC input voltage, output current and temperature are also possible causes. Normal operation should be within the power dissipation rating, if however the rating is exceeded for a continued period, the junction temperature Tj will rise and the TSD circuit will be activated and turn all output pins OFF.


Baking is required before using Products of which storage time is exceeding the recommended storage time period. Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect product performance and reliability. Lab 9 in this note.

Please be sure to implement, at your own responsibilities, adequate safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which a failure or malfunction of our Products may cause.

ROHM does not warrant that foregoing information or data will not datasjeet any intellectual property rights or any other rights of any third party regarding such information or data.

ROHM shall not be in any way responsible or liable for infringement of any intellectual property rights or other damages arising from use of such information or data.: We also recommend using reverse polarity diodes in series or a bypass between all pins dataeheet the VCC pin. Incorrect mounting may result in damaging the IC. Therefore, in case you use such information, you are solely responsible for it and you must exercise your own independent verification and judgment in the use of such information contained in this document.

Please take special care under dry condition e. The absolute maximum rating of the Pd stated in this specification is when the IC is mounted on a 70mm X 70mm X 1.

The product described in this specification is designed to be used with ordinary electronic equipment or devices such as audio-visual equipment, office-automation equipment, communications devices, electrical appliances, and electronic toys. Their operation can result in mutual interference between circuits and can cause malfunctions and, in turn, physical damage to or destruction of the chip.

Ceramic capacitors can be used for compensation of the output capacitor phase. Parasitic diodes inevitably occur in the structure of the IC. Low ESR ceramic capacitor can be used as output capacitor.
