It draws just 15 µA quiescent current and delivers a PSRR of 65 dB at 100 Hz, rolling off to 40 dB at 1 MHz — the high-frequency rejection is what makes this part a fit for powering sensitive RF or analog front-end rails where switching noise from a buck converter would otherwise couple into the signal path. ## Dropout, protection, and temperature grade Maximum dropout is 145 mV at the full 300 mA load, so the input rail needs only 3.345 V to maintain regulation — this matters in battery-powered designs where the cell voltage sags under load. The junction temperature range spans -40°C to 125°C, covering industrial and under-hood automotive environments. On-chip protection includes over-current, over-temperature, and under-voltage lockout (UVLO), which prevents the output from turning on until the input is stable. ## Package and control features for compact designs Housed in a 5-pin SOT-23-5 (SC-74A) package, the footprint is small enough for space-constrained portable or sensor-node PCBs. The Enable pin allows external on/off control, and the Soft Start feature limits inrush current during power-up — useful when the regulator feeds a capacitive load or a module that must sequence after the main rail is stable. ## Lifecycle and sourcing reality This part carries an active lifecycle status — no end-of-life notice, no successor to plan for. It is suitable for both new designs and production replenishment.","metaTitle":"TPS7A2032PDBVR LDO, 300mA, 3.2V Fixed, SOT-23-5","metaDescription":"Texas Instruments TPS7A2032PDBVR LDO regulator: 300mA output, 3.2V fixed, 15µA Iq, PSRR 65dB-40dB (100Hz-1MHz).
