It delivers up to 500 mA from a 40 V maximum input, making it suited for directly regulating battery voltage in automotive body electronics, infotainment, and ADAS sensor modules. With a 70 dB PSRR at 1 kHz, this LDO attenuates ripple from upstream switching converters or alternator noise, keeping the downstream analog or RF supply clean. The 26 µA quiescent current keeps the regulator's own draw low on always-on battery lines. ## Wide input range and thermal package The input voltage range extends to 40 V, covering automotive cold-crank dips and load-dump transients without an external clamp. The adjustable output is set between 1.2 V and 18 V via an external resistor divider. The 8-PowerSOIC package with an exposed PowerPad (8-SO PowerPad) pulls heat into the PCB copper plane. The 0.570 V maximum dropout at 500 mA means the input-to-output headroom must stay above that threshold to maintain regulation at full load. Operating temperature spans -40°C to 125°C ambient, matching the AEC-Q100 Grade 1 automotive qualification. Protection features include overcurrent, overtemperature, and undervoltage lockout (UVLO). ## Active lifecycle and sourcing posture Texas Instruments lists the TPS7B8601DQDDARQ1 as Active, with ROHS3 compliance.","metaTitle":"TPS7B8601DQDDARQ1 LDO, 500 mA, 40 Vin, AEC-Q100","metaDescription":"Texas Instruments TPS7B8601DQDDARQ1 adjustable LDO, 500 mA output, 40 V max input, 70 dB PSRR at 1 kHz, AEC-Q100 qualified.
