TLF80511TC

The TLF80511 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 VQ,nom = 5 V with ±2 % precision. The TLF80511 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 TLF80511 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 TLF80511 can be also used in all other applications requiring a stabilized 5 V supply voltage.
