TPS731 的說明
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.
