7.1 Overview

The TPS715-Q1 low-dropout regulator (LDO) consumes only 3.2 μA (typ) of quiescent current across the entire output current range, while offering a wide input voltage range and low-dropout voltage in small packaging. The device, which operates over an input range of 2.5 V to 24 V, is stable with any output capacitor greater than or equal to 0.47 μF. The low quiescent current across the complete load current range makes the TPS715-Q1 optimal for powering battery-operated applications. The TPS715-Q1 has internal soft-start to control inrush current into the output capacitor. This LDO also has overcurrent protection during a load-short or fault condition on the output.
