The 26 µA quiescent current keeps the always-on draw low enough that a 12 V battery parked for a month loses less than 0.02 Ah to the regulator alone – relevant for modules that stay powered during ignition-off. ## 70 dB PSRR at 1 kHz – filtering switching noise The 70 dB power-supply rejection ratio at 1 kHz attenuates ripple from a downstream DC-DC converter by a factor of 3160. For a 5 V rail feeding an analog sensor or ADC reference, this keeps the supply-induced noise floor below 10 µV – the regulator's own output noise, not the input ripple, becomes the limit. ## TO-252 package – thermal pad and board layout Housed in a TO-252-3 (DPak) surface-mount package with an exposed metal tab on the bottom side. The tab is the output terminal and the primary heat path – the PCB copper area under it sets the junction-to-ambient thermal resistance.","metaTitle":"TPS7B8850QKVURQ1R2 Texas Instruments LDO, 500 mA, 40 V","metaDescription":"Texas Instruments TPS7B8850QKVURQ1R2 automotive LDO, 500 mA output, 40 V input, 70 dB PSRR at 1 kHz, AEC-Q100, active production, TO-252.
