Description for the TPS784-Q1

The TPS784-Q1 ultra low-dropout regulator (LDO) is a small, lowquiescent current LDO that can source 300 mA with excellent line and load transient performance.

The low output noise and great PSRR performance make the device suitable to powersensitive analog loads. The TPS784-Q1 is a flexible device for post regulationbecause this device supports an input voltage range from 1.65 V to 6.0 V and offers an adjustableoutput range of 1.2 V to 5.5 V. The device also features fixed output voltages from 0.65 V to5.0 V for powering common voltage rails.

The TPS784-Q1 offers foldback current limit to reduce powerdissipation during over current condition. The EN input helps with power sequencing requirements ofthe system. The internal soft-start provides a controlled startup reducing the inrush currentallowing for lower input capacitance to be used.

The TPS784-Q1 provides an active pulldown circuit to quickly dischargeoutput loads when disabled.
