TPS73643DBVR

The TPS73643DBVR is a 4.3V fixed output low-dropout (LDO) Linear 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 device uses an advanced BiCMOS process to yield high precision while delivering very low-dropout (LDO) voltages and low ground pin current. Current consumption, when not enabled, is under 1µA and ideal for portable applications. The extremely low output noise is ideal for powering VCOs. This device is protected by thermal shutdown and foldback current limit.
