The TPS7A05 is an ultra-small, low quiescent current low-dropout regulator (LDO) that can
source 200 mA with excellent transient performance. This device has an output range of 0.8 V to 3.3
V with a typical 1% accuracy.
The TPS7A05, with ultralow IQ (1 µA), is designed specifically for
battery-powered applications where very-low quiescent current is a critical parameter for extending
battery life. The device can be operated from rechargeable Li-Ion batteries, Li-primary battery
chemistries such as Li-SOCl2, Li-MnO2, as well as two- or three-cell alkaline batteries.
The TPS7A05 is available with an active pulldown circuit to quickly discharge the output
The TPS7A05 is fully specified for TJ = –40°C to +125°C operation,
and is available in standard X2SON (DQN), SOT-23 (DBV), and DSBGA (YKA) packages.
