TPS7A05 - Texas Instruments

TPS7A05 Low-Dropout Regulator

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), consumes very-low quiescent current for extending battery life in battery-powered applications. The de.
