The TPS73133DBVTG4 is a Cap-free NMOS Low Dropout Regulator with reverse current protection. This regulator uses a new topology an NMOS pass element in a voltage-follower configuration. This topology is stable using output capacitors with low ESR and even allows operation without a capacitor. It also provides high reverse blockage (low reverse current) and ground pin current that is nearly constant over all values of output current. The TPS73101 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.
