TheTLS710B0is a low dropout linear voltage regulator for load current up to 100 mA. An input voltage of up to 40 V is regulated to VQ,nom= 5 V with ± 2% precision. The TLS710B0, with a typical quiescent current of 40 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 250 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 TLS710B0 suitable to supply automotive systems with start-stop requirements. The device can be switched on and off by the Enable feature. In addition, the TLS710B0’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, overcurrent and overtemperature.
