That 0.38 V ceiling is the number to budget for worst-case headroom — not the typical figure — and it sets the minimum input voltage for the design. ## PSRR 73 dB to 57 dB at 120 Hz — ripple rejection across the line Power-supply rejection ratio is specified at 73 dB to 57 dB at 120 Hz, which is the full-wave rectifier ripple frequency. The 73 dB figure applies at lower dropout headroom; as the input-to-output differential narrows, PSRR drops toward 57 dB. ## Through-hole TO-220-5 — thermal and board-fit The TO-220-5 formed-leads package (supplier device package TO-220-5) is a through-hole power package. The formed leads are spaced for standard 0.100-inch pitch holes.","metaTitle":"LP3852ET-3.3/NOPB LDO Regulator, 3.3V Fixed, 1.5A, TO-220-5","metaDescription":"Texas Instruments LP3852ET-3.3/NOPB, 1.5A LDO, fixed 3.3V output, 0.38V dropout at full load, -40°C to 125°C, active production.
