Texas Instruments  PS7A0527PDBZR

The TPS7A05 is an ultra-small, low quiescent current low-dropout regulator (LDO) that cansource 200 mA with excellent transient performance. This device has an output range of 0.8 V to 3.3V with a typical 1% accuracy.

The TPS7A05, with ultralow IQ (1 µA), consumes very-low quiescentcurrent for extending battery life in battery-powered applications. The device can be operated fromrechargeable Li-Ion batteries, Li-primary battery chemistries such as Li-SOCl2, Li-MnO2, as well astwo- or three-cell alkaline batteries.

The TPS7A05 is available with an active pulldown circuit to quickly discharge the outputwhen disabled.

The TPS7A05 is fully specified for TJ = –40°C to +125°C operation,and is available in standard X2SON (DQN), SOT-23 (DBV and DBZ), and DSBGA (YKA) packages.
