TPS7A05 Low-Dropout Regulator (LDO)
Texas Instruments' TPS7A05 ultra-low Iq, 200 mA LDO in a small-size package
Texas Instruments' TPS7A05 is an ultra-small, low quiescent current 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 ultra-low IQ (1 µA) consumes very-low quiescent current for extending battery life in battery-powered applications. This LDO 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. It is available with an active pulldown circuit to quickly discharge the output when 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 DSBGA (YKA) packages.
