Precise control of output voltage and current

TPS76801QD General Description

The TPS76801QD by Texas Instruments is a dependable choice for voltage regulation needs, offering a fixed output voltage of 1.8V and a maximum output current of 1A. With an input voltage range of 2.7V to 10V, this LDO regulator is versatile and applicable in various scenarios. Its low dropout voltage of just 150mV under full load ensures a consistent output voltage, even when the input voltage approaches the desired level. Moreover, the device boasts a meager quiescent current of 75µA, contributing to reduced power consumption and prolonged battery life, particularly beneficial for portable devices
