Линейные регуляторы TPS73201DRBT

Стабилизатор с малым падением напряжения , регулируемый, 1.7В до 5.5В (Vin), 40мВ, 1.2В до 5.5В/250мА

The TPS73201DRBT is a low-dropout (LDO) Voltage Regulator uses 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 TPS732 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 1µA and ideal for portable applications. The extremely low output noise is ideal for powering VCOs. This device is protected by thermal shutdown and fold-back current limit. The increased insensitivity to the output capacitor value and type makes this linear regulator an ideal choice when powering a load where the effective capacitance is unknown.
