TPS71519DCKR

The TPS715 low-dropout (LDO) linear regulator is a low quiescent current device offering the advantages of miniature packaging, wide input voltage range, and low-power operation. As such, the TPS715 is designed for battery-powered applications and can serve as a power management companion for low-power microcontrollers. The TPS715 is available in both fixed-voltage and adjustable-voltage versions. For greater flexibility or higher output voltages, the adjustable version uses feedback resistors to set the output voltage from 1.205V to 15V. The TPS715 LDO supports a typical dropout voltage of 415mV at a load current of 50mA. The low quiescent current (typically 3.2μA) remains stable across the full output load current range (0mA to 50mA). The TPS715 also features an internal soft-start function to reduce inrush current. Built-in overcurrent limiting helps protect the regulator during load short-circuit or fault conditions.
