TPS71501 Linear Regulator IC Chip

TPS71501(50 mA, 24 V, 3.2μA Supply Current,Low-Dropout Linear Regulator)

Introduction

The TPS71501/-25/-30/-33/-50(TPS715XX) low-dropout (LDO) voltage regulators offer the benefits of high input voltage, low-dropout voltage, low-power operation, and miniaturized packaging. The devices, which operate over an input range of 2.5 V to 24 V, are stable with any capacitor(≥0.47 μF). The low dropout voltage and low quiescent current allow operations at extremely low power levels. Therefore, the devices are ideal for powering battery management ICs. Specifically, since the devices are enabled as soon as the applied voltage reaches the minimum input voltage, the output is quickly available to power continuously operating battery charging ICs.

A PMOS pass element replaces the typical PNP pass transistor.Because the PMOS pass element behaves as a low-value resistor, the low dropout voltage, typically 415 mV at 50 mA of load current, is directly proportional to the load current.The low quiescent current (3.2 μA typically) is stable over the entire range of output load current (0 mA to 50 mA).
