TPS72101DBVTG4 Description
The TPS72101DBVTG4 LDO regulator is available in fixed voltage options that are commonly used to power the latest DSPs and microcontrollers with an adjustable option ranging from 1.22 V to 2.5 V. The TPS72101DBVTG4 can be used in a wide variety of applications ranging from portable, battery-powered equipment to PC peripherals. The TPS72101DBVTG4 features operation over a wide range of input voltages (1.8 V to 5.5 V) and low dropout voltage (150 mV at full load). Therefore, compared to many other regulators that require 2.5-V or higher input voltages for operation, the TPS72101DBVTG4 can be operated directly from two AAA batteries. Also, the typical quiescent current (ground pin current) is low, starting at 85 μA during normal operation and 1 μA in shutdown mode.
