TPS7301QP

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

The TPS7301QP is a micropower low-dropout (LDO) voltage regulator from the TPS73xx family, featuring an integrated delayed microprocessor-reset function. It provides an adjustable output voltage programmable between 1.2 V and 9.75 V using external resistors. The device utilizes a PMOS pass element to achieve very low dropout voltage and quiescent current that remains independent of load current. It includes active-low reset signaling with a typical 200-ms pulse width upon undervoltage recovery. The regulator supports an output current range up to 500 mA and operates within a junction temperature range of -40°C to 125°C.
