TheTLS715B0is a low dropout linear voltage regulator for load current up to 150 mA. An input voltage of up to 40 V is regulated to VQ,nom= 5 V with ± 2% precision. The TLS715B0, with a typical quiescent current of 36 μA, is the ideal solution for systems requiring very low operating current, such as those permanently connected to the battery. It features a very low dropout voltage of 200 mV, when the output current is less than 100 mA. In addition, the dropout region begins at input voltages of 4.0 V (extended operating range). This makes the TLS715B0 suitable to supply automotive systems with start-stop requirements. The device is designed for the harsh environment of automotive applications. Therefore standard features like output current limitation and over-temperature shutdown are implemented and protect the device against failures like output short circuit to GND, overcurrent and overtemperature. The TLS715B0 can be also used in all other applications requiring a stabilized 5 V supply voltage.
