TPS73201DRBT Capacitor-Free, NMOS, 250mA, Low-Dropout Regulator With Reverse Current Protection QFN spot stock

Product Descriptions

The TPS732 low-dropout (LDO) voltage regulator  uses an NMOS pass transistor in a voltage-follower  configuration. This topology is stable using output  capacitors with low equivalent series resistance  (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 values of output current.

The TPS732 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 less than 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.
