DESCRIPTIONThe TPS736xx family of low-dropout (LDO) linearvoltage regulators uses a new topology: an NMOSpass element in a voltage-follower configuraTIon. Thistopology is stable using output capacitors with lowESR, and even allows operaTIon without a capacitor.It also provides high reverse blockage (low reversecurrent) and ground pin current that is nearly constantover all values of output current.The TPS736xx uses an advanced BiCMOS processto yield high precision while delivering very lowdropout voltages and low ground pin current. CurrentconsumpTIon, when not enabled, is under 1mA andideal for portable applications. The extremely lowoutput noise (30mVRMS with 0.1mF CNR) is ideal forpowering VCOs. These devices are protected bythermal shutdown and foldback current limit.
