TPS736 Capacitor-Free, NMOS, 400mA, Low-Dropout Regulator With Reverse Current

Protection

1 Features

• Stable with no output capacitor or any value or

type of capacitor

• Input voltage range of 1.7V to 5.5V

• Ultra-low dropout voltage: 75mV typ

• Excellent load transient response—with or without

optional output capacitor

• NMOS topology delivers low reverse leakage

current

• Low noise: 30μVRMS typ (10Hz to 100kHz)

• 0.5% initial accuracy

• 1% overall accuracy over line, load, and

temperature

• Less than 1μA max IQ in shutdown mode

• Thermal shutdown and specified min/max current

limit protection

• Available in multiple output voltage versions:

– Fixed outputs of 1.20V to 5.0V

– Adjustable output from 1.20V to 5.5V

– Custom outputs available

2 Applications

• Portable-, battery-powered equipment

• Post-regulation for switching supplies

• Noise-sensitive circuitry such as VCOs

• Point of load regulation for DSPs, FPGAs, ASICs,

and microprocessors

3 Description

The TPS736 low-dropout (LDO) linear voltage

regulator uses a new topology: an NMOS pass

transistor in a voltage-follower configuration. This

topology is stable using output capacitors with low

ESR, and even allows operation without a capacitor.

The device also provides high reverse blockage (low

reverse current) and ground pin current that is nearly

constant over all output current values.

The TPS736 uses an advanced BiCMOS process

to yield high precision while delivering very low

dropout voltages and low ground pin current. Current

consumption, when not enabled, is under 1μA and

designed for portable applications. The extremely low

output noise (30μVRMS with 0.1μF CNR) is designed

for powering VCOs. This device is protected by

thermal shutdown and foldback current limit.
