PSRR rolls off above the regulator's unity-gain crossover; for higher-frequency noise (above ~100 kHz), the attenuation drops to the output capacitor's impedance divider — a low-ESR ceramic output cap maintains rejection into the MHz range. ## Quiescent current and protection for battery-powered designs Typical quiescent current is 55 µA, with a maximum supply current of 270 µA — the regulator's own draw stays below 300 µA even at no load, suiting always-on domains in battery-operated equipment where every microamp counts. Built-in protection includes over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) — the UVLO ensures the output stays off until the input rail is high enough to maintain regulation, preventing brownout glitches on downstream logic. ## Temperature grade and board integration Surface-mount on a 5-pin SC-70-5 footprint with 0.65 mm pitch — the enable pin allows external on/off control, and the fixed 3 V output eliminates the need for feedback resistors, saving two components in the BOM.","metaTitle":"TI TLV70030DCKT LDO Regulator, 3V Fixed, 200mA, SC-70-5","metaDescription":"Texas Instruments TLV70030DCKT LDO, 3V fixed output, 200mA, 68dB PSRR at 1kHz, SC-70-5.
