TPS73131DBVR
无电容， NMOS器，150mA低压降稳压器，具有反向电流保护 Cap-Free, NMOS, 150mA Low Dropout Regulator with Reverse Current Protection
The TPS731xx family of low-dropout LDO linear voltage regulators uses a new topology: an NMOS pass element 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 TPS731xx 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 1 µA and ideal for portable applications. The extremely low output noise 30 µVRMS with 0.1-µF CNR is ideal for powering VCOs. These devices are protected by thermal shutdown and foldback current limit.
