Lab 9 in this note. For example, in case a resistor and a transistor datasyeet connected to the pins as shown in the figure below then: 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.
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. Otherwise bent leads may occur due to excessive stress applied when dropping of a carton.

Therefore, when actually using the chip, ensure that the generated heat does not exceed the Pd rating. 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.
Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect datasheet performance and reliability.
If there are any differences in translation version of this document formal version takes priority Application example ROHM cannot provide adequate confirmation of datashwet.
Documents Flashcards Grammar checker. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the Pd rating. Similarly, care must be taken to avoid wiring pattern fluctuations in any datashest external component GND. Incorrect mounting may result in damaging the IC.
Please take proper caution in your manufacturing process and storage so that voltage exceeding the Products datxsheet rating will not be applied to Products.
ROHM does not warrant that foregoing information or data will not infringe any intellectual property rights or any other rights of any third party regarding such information or data.
After the Tj falls below the TSD threshold the circuits are automatically restored to normal operation. 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.
Also, shorts datasneet by dust entering between the output, input and GND pin may result in damaging the IC. On the reverse side of the package this product has an exposed heat pad for improving the heat dissipation.
Low Quiescent Current LDO Regulator
Integrated thermal shutdown to protect the IC from overheating at overload conditions. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit.
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. 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 dataheet and turn all output dataaheet OFF.
In this event it also becomes impossible to determine the cause of the damage e. 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. Parasitic diodes inevitably occur in the structure of the IC.
High output voltage accuracy: Note that the TSD circuit operates in a situation that exceeds the absolute datashest 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. Low ESR ceramic capacitor can be used as output capacitor. The following are examples of safety measures: Baking is required before using Products of which storage time is exceeding the recommended storage time period.

Includes switch Integrated overcurrent protection to protect the IC from damage caused by output short-circuiting. 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 do not employ any method in which parasitic diodes can operate such as applying a voltage to an input daatasheet that is lower than the P substrate GND.
In case problems arise within the actual operating range, use countermeasures such as adjusting the output capacitance. 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. Their operation can result in mutual interference between circuits datashdet can cause malfunctions and, datassheet turn, physical damage to or destruction of the chip.
Ceramic capacitors can be used for compensation of the output capacitor phase. It is strongly recommended to confirm solderability before using Products of which storage time is exceeding the recommended storage time period.
Please take special care under dry condition e. A customer may use this translation version only for a reference to help reading the formal version. The amount of heat generated depends on the voltage difference across the input and output, load current, and bias current. Transient characteristics should be sufficiently verified.
