TPS73225MDBVREP

无电容NMOS 250 mA低压差具有反向电流保护稳压器 CAP-FREE NMOS 250-mA LOW DROPOUT REGULATOR WITH REVERSE CURRENT PROTECTION

The TPS732xx family of low–dropout LDO voltage regulators 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 TPS732xx uses an advanced BiCMOS process to yield high precision while delivering low dropout voltages and low ground pin current. Current consumption, when not enabled, is under 1 µA and ideal for portable applications. The 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.
