TPS7301QD

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TPS7301Q is a micropower low-dropout (LDO) voltage regulator featuring an integrated delayed microprocessor-reset function. It provides an adjustable output voltage range from 1.2 V to 9.75 V, set via an external resistor divider. The device utilizes a PMOS pass element to achieve very low dropout voltage and quiescent current that remains independent of the load current. It includes active-low reset signal generation with a typical 200-ms pulse width upon undervoltage recovery.
