7 Detailed Description

7.1 Overview

The TLV709 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 30 V, is stable with any output capacitor greater than

or equal to 1 μF. The low quiescent current across the complete load current range makes the TLV709 a great

choice for powering battery-operated applications. The TLV709 has an 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.
