With a 15 V absolute maximum input, the part tolerates 12 V intermediate rails and 5 V rails with margin for transients. ## PSRR at 120 Hz — filtering the rectified line ripple Power supply rejection ratio is 65 dB at 120 Hz, which attenuates the 100/120 Hz ripple from a full-wave rectified mains supply by a factor of roughly 1800 — a 1 Vpp ripple at the input becomes about 0.55 mVpp at the output. ## Protection and quiescent budget Built-in overcurrent, overtemperature, and short-circuit protection eliminate the need for external supervisory circuits on the output rail. Quiescent current is 10 mA — this is the standing draw from the input rail when the output is unloaded, relevant for always-on or battery-backed rails where every milliamp counts. ## Lifecycle and compliance — active and ROHS3 ROHS3 compliant — the part contains none of the six restricted substances plus the four phthalates under EU Directive 2011/65/EU, so it ships without a RoHS exemption statement.","metaTitle":"Infineon IFX1117GSV33 LDO Regulator, 3.3V Fixed, 1A, SOT-223","metaDescription":"Infineon IFX1117GSV33 linear regulator, fixed 3.3V output, 1A, 1.4V dropout, 65dB PSRR at 120Hz.
