TEXAS INSTRUMENTS Fixed LDO Voltage Regulator 5V 50mA TO-92-3

The TEXAS INSTRUMENTS Fixed LDO Voltage Regulator is an ultra-low quiescent current device featuring low dropout voltage and low current in standby mode. Designed with less than 15μA quiescent current at a 100μA load, this regulator is ideally suited for automotive and other battery-operated systems requiring efficient power management.

This regulator retains all the standard features of low dropout regulators, including a low dropout PNP pass device, short circuit protection, reverse battery protection, and thermal shutdown. It provides reliable performance with a 40V maximum operating voltage limit and a wide operating temperature range from -40°C to 125°C.

The device offers a ±3% output voltage tolerance over the entire output current, input voltage, and temperature range. It is available in a fixed 5V output voltage version, providing up to 50mA of output current with a typical dropout voltage of 200mV. The through-hole mounting and TO-92-3 package make it straightforward to integrate into various circuit designs.
