3 Description

The TPS736-Q1 low-dropout (LDO) linear voltage

regulator uses an NMOS topology consisting of

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. This topology also provides high

reverse blockage (low reverse current) and ground pin

current that is nearly constant over all values of output

current.

The TPS736-Q1 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

ideal for portable applications. The extremely low

output noise (30μVRMS with 0.1μF CNR) is ideal for

powering VCOs. This device is protected by thermal

shutdown and foldback current limit.
