3 Description
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.
The TPS785-Q1 provides an active pulldown circuit to
quickly discharge output loads when disabled.
