PSRR is specified at 60dB at 100Hz — this is a line-frequency rejection number, not a wideband spec; above a few kilohertz the PSRR rolls off, so upstream switching noise above 100kHz passes through unless filtered ahead of the LDO. Quiescent current is 125 µA typical — low enough for always-on rails in battery-backed industrial controllers, but not in the micropower class; the Iq is the standing load on the input when the output is unloaded. ## Input range, adjustable output, and protection set Input voltage range goes up to 5.5V maximum — this is a 5V-rail LDO, not a wide-VIN part; the adjustable output spans 1.5V to 5V, set by an external resistor divider on the feedback pin. Control features include an Enable pin for sequencing, a Power Good flag, and a Reset Output — the reset output is a sequenced open-drain signal that tracks the output regulation, useful for FPGA or processor core rail sequencing.","metaTitle":"TPS75401QPWP LDO, 2A adjustable, 60dB PSRR, HTSSOP-20","metaDescription":"Texas Instruments TPS75401QPWP adjustable LDO, 2A output, 60dB PSRR at 100Hz, 125µA Iq.
