Quiescent current is 100 µA typical at no load, rising to 2 mA maximum under full supply current — low enough for always-on ECU domains that must stay powered during key-off to maintain wake-up circuits. PSRR is 66 dB at 100 Hz — the ripple rejection at alternator fundamental frequency attenuates the 100 Hz ripple from the rectified alternator output before it reaches the downstream microcontroller supply rail. Supplied in a PG-DSO-14 package (14-SOIC, 3.90 mm body width) — the exposed pad on the underside requires a thermal via array to the ground plane to keep junction temperature below the 150°C limit at full load in a 85°C ambient. Enable and Reset control pins are available — the enable pin allows sequenced power-up, and the reset output provides a power-good flag to the ECU microcontroller without an external supervisor IC.","metaTitle":"TLE42994GMV33XUMA3 LDO, 150mA, 3.3V, AEC-Q100, PG-DSO-14","metaDescription":"Infineon TLE42994GMV33XUMA3 active LDO, 150mA fixed 3.3V output, 45V input max, AEC-Q100 qualified.
