Input voltage range extends to 45 V maximum, making it suitable for automotive battery rails (12 V/24 V nominal) that see load-dump transients without requiring an external pre-regulator. Quiescent current is 70 µA typical — low enough for always-on modules in battery-backed systems where every microamp extends standby life. ## 68 dB PSRR and integrated protection Power-supply rejection ratio is 68 dB at 100 Hz — this attenuates ripple from rectified mains or alternator output by a factor of ~2500, keeping the 3.3 V rail clean for sensitive analog or microcontroller supplies. On-chip protection includes over-temperature shutdown, reverse polarity blocking, and short-circuit current limiting, so the regulator survives a miswired battery or a downstream fault without external clamp diodes. The PG-SOT223-4 package (TO-261AA footprint) is a standard SMD power package with an exposed tab for heat sinking — layout guidelines are well established and the pad pattern is shared across many LDOs in this class.","metaTitle":"TLE42662GSV33HTMA1 LDO, 3.3V Fixed, 100mA, PG-SOT223-4","metaDescription":"Infineon TLE42662GSV33HTMA1 linear voltage regulator, 3.3V fixed output, 100mA, 45V input max, 68dB PSRR, active production.
