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.
