description

The TPS760xx is a 50mA, low dropout (LDO) voltage regulator designed specifically for battery-powered
applications. A proprietary BiCMOS fabrication process allows the TPS760xx to provide outstanding
performance in all specifications critical to battery-powered operation.

The TPS760xx is available in a space-saving SOT–23 package and operates over a junction temperature range
of –40°C to 125°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
