The Enable, Power Good, and Tracking control features allow sequencing against an FPGA or SoC power-up order: Power Good asserts when the output reaches ~92% of the set voltage, and the Tracking pin lets the output follow an external reference ramp during start-up. Quiescent current is 115 µA typical, rising to 1.5 mA maximum under all conditions. For a battery-powered sensor node that spends most of its time in sleep, the 115 µA Iq is the floor — the regulator's own draw plus the load's sleep current sets the battery life ceiling.","metaTitle":"TPS74301RGWR Texas Instruments LDO, 1.5A","metaDescription":"Texas Instruments TPS74301RGWR LDO voltage regulator, 1.5 A output, 0.8-3.6 V adjustable, 120 mV dropout at 1.5 A.
