description

The TPS760xx is a 50 mA, 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.
