Automotive Low Dropout (LDO), Linear Voltage Regulator OPTIREG™ TLS715B0EJ V50
for load current up to 150 mA

THERMALMODEL=10

The TLS715B0EJ V50 is 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 can be switched on and off by the Enable feature as described on Chapter “Enable” on Page 15.
In addition, the TLS715B0’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-temperature. The TLS715B0 can be also used
in all other applications requiring a stabilized 5 V supply voltage.
