Description

General part information

TPS785-Q1 Series

The TPS785-Q1 ultra low-dropout regulator (LDO) is a small, low quiescent current LDO that can source 1 A with excellent line and load transient performance.

The low output noise and great PSRR performance make the device suitable to power-sensitive analog loads. The TPS785-Q1 is a flexible device for post regulation because this device supports an input voltage range from 1.7 V to 6.0 V and offers an adjustable output range of 1.2 V to 5.5 V. The device also features fixed output voltages from 0.65 V to 5.0 V for powering common voltage rails.

The TPS785-Q1 offers foldback current limit to reduce power dissipation during a over current condition. The EN input helps with power sequencing requirements of the system. The internal soft-start provides a controlled start up reducing the inrush current allowing for lower input capacitance to be used.
