Description

The TLF80511EJ is a linear low dropout voltage regulator for load currents up to 400 mA. An input voltage of up

to 40 V is regulated to

V

The TLF80511EJ with a typical quiescent current of 38 µA, is the ideal solution for systems requiring very low

operating currents, such as those permanently connected to a battery.

It features a very low dropout voltage of 100 mV, when the output current is less than 100 mA. In addition, the

dropout region begins at input voltages of 3.3 V (extended operating range). This makes the TLF80511EJ suitable

to supply automotive systems.

In addition, the TLF80511’s new fast regulation concept requires only a single, 1 µF output capacitor to maintain

stable regulation.

The device is designed for the harsh environment of automotive applications. Therefore standard features like

output current limitation and overtemperature shutdown are implemented and protect the device against failures

like output short circuit to GND, over-current and over-temperatures. The TLF80511EJ can be also used in all

other applications requiring a stabilized 5 V or 3.3 V supply voltage.
