资 源 简 介
The TPS722xx family of LDO regulators is available in fixed voltage opTIons that are commonly used to power the latest DSP’s and microcontrollers with an adjustable opTIon ranging from 1.22 V to 2.5 V. These regulators can be used in a wide variety of applicaTIons ranging from portable, battery-powered equipment to PC peripherals. The family features operaTIon over a wide range of input voltages (1.8 V to 5.5 V) and low dropout voltage (50 mV at full load). Therefore, compared to many other regulators that require 2.5-V or higher input voltages for operation, these regulators can be operated directly from two AAA batteries. Also, the typical quiescent current (ground pin current) is low, starting at 85 uA during normal operation and 1 uA in shutdown mode.
