6.1 Overview

The TPS736 low-dropout linear regulator operates down to an input voltage of 1.7 V and supports output voltages down to 1.2 V while sourcing up to 400 mA of load current. This linear regulator uses an NMOS pass transistor with an integrated 4-MHz charge pump to provide a dropout voltage of less than 200 mV at full load current. This unique architecture also permits stable regulation over a wide range of output capacitors. In fact, the TPS736 device does not require any output capacitor for stability. The increased insensitivity to the output capacitor value and type makes this linear regulator an ideal choice when powering a load where the effective capacitance is unknown.

The TPS736 also features a noise reduction (NR) pin that allows for additional reduction of the output noise. With a noise reduction capacitor of 0.01 µF connected from the NR pin to GND, the TPS73615 output noise can be as low as 12.75 µVRMS. The low noise output featured by the TPS736 makes the device well-suited for powering VCOs or any other noise sensitive load.
