Description

The TPS784 is an adjustable 300-mA ultra low-dropout regulator (LDO) with a low quiescent current. This device is available in a small 5-pin, 2.9-mm × 1.6-mm, SOT-23 package and has an excellent line and load transient performance. The low output noise and great PSRR performance make this device suitable to power-sensitive analog loads. The TPS784 is a flexible device for post regulation because this device supports an input voltage range from 1.65 V to 6.0 V and offers an adjustable output range of 1.2 V to 5.5 V. The TPS784 offers foldback current limit to reduce power dissipation during over current condition. The EN input helps with power sequencing requirements of the system. The internal soft-start provides a controlled startup reducing the inrush current and allowing for a small input capacitor to be used. The TPS784 provides an active pulldown circuit to quickly discharge output loads when disabled. The TPS784 is an adjustable 300-mA ultra low-dropout regulator (LDO) with a low quiescent current.
