Its 60 dB PSRR at 1 kHz means it cleans up switching supply ripple well enough to feed low-noise analog front-ends or quiet digital rails. The Enable pin lets a supervisor or GPIO sequence the rail on/off without a series FET. Enable is active-high; floating it turns the output off. ## Temperature range and package — board fit Rated -40°C to 125°C, this regulator handles engine-bay ambient or industrial enclosures near hot power stages. Surface-mount only, so plan for reflow or hand-solder with a fine tip. The 100 µA quiescent current and 140 µA max supply current make it a candidate for battery-powered gear where every microamp of standby matters. ## Protection set and output tolerance Integrated over-current, over-temperature, and reverse polarity protection cover the common fault cases. Output is fixed at 3 V — no resistor divider needed, no adjustment pin to bypass. The Fixed output type means the BOM stays simple: just an input cap and an output cap per the datasheet recommendation. ## Lifecycle and sourcing posture No LTB or NRND flags — this part is current for new designs and production replenishment.","metaTitle":"TPS76430DBVR LDO Regulator, 3V Fixed Output, 150mA, SOT-23-5","metaDescription":"TI TPS76430DBVR linear regulator: fixed 3V output, 150mA, 60dB PSRR at 1kHz, -40°C to 125°C, SOT-23-5.
