Input voltage tolerance extends to 40 V, so the part survives 12 V system load dumps and 24 V truck battery rails without an external clamp. Protection circuits for overcurrent, overtemperature, reverse polarity, and short circuit are integrated, reducing external component count. ## PSRR and quiescent current for always-on loads Power supply rejection ratio is 60 dB at 100 Hz — this attenuates rectified alternator ripple or DC-DC switching ripple by a factor of 1000 at that frequency, keeping the output clean for sensitive loads like CAN transceivers or analog sensor front-ends. The low Iq suits always-on modules in body controllers or gateway ECUs where the regulator stays powered even when the system sleeps. ## TO-263 package and thermal layout Housed in a TO-263-4 (D2Pak) surface-mount package with three leads plus the exposed tab (PG-TO263-3-1 supplier designation). Output is fixed 8.5 V; no external resistor divider needed. The single regulator channel and positive output configuration simplify the bill of materials for a dedicated 8.5 V rail. ## Active production, sourced per BOM No pin-compatible second source is recorded in this series.","metaTitle":"IFX25001TC Infineon 400mA Fixed 8.5V LDO, AEC-Q100, TO-263","metaDescription":"Infineon IFX25001TC 400mA LDO, fixed 8.5V output, 40V input max, AEC-Q100 automotive grade, -40 to 125°C.
