TPS72101DBVT

The TPS72101DBVT is a low input voltage LDO Linear Regulator commonly used to power the latest DSPs and microcontrollers. It features operation over a wide range of input voltages and low dropout voltage. Therefore, compared to many other regulators that require 2.5V or higher input voltages for operation, this regulator can be operated directly from two AAA batteries. Also, the typical quiescent current is low, starting at 85µA during normal operation and 1µA in shutdown mode. This regulator can be operated very efficiently and in a battery-powered application, help extend the longevity of the device. Similar LDO regulator requires 1µF or larger output capacitors for stability. However, this regulator uses an internal compensation scheme that stabilizes the feedback loop over the full range of input voltages and load currents with output capacitances as low as 0.1µF. Ceramic capacitors of this size are relatively inexpensive and available in small footprints.
