Maximum input voltage is 5.5 V, and the maximum dropout voltage is 0.35 V at the full 150 mA load — the headroom between the input rail and 2.5 V must stay above this figure across the load range to maintain regulation. ## PSRR and quiescent current for noise-sensitive rails Power-supply rejection ratio is specified at 60 dB at 100 Hz, rolling off to 50 dB at 10 kHz — this attenuation profile suits analog front-end and RF supply rails where low-frequency ripple from a switching pre-regulator must be suppressed before reaching the load. Quiescent current is 55 µA typical, with a maximum supply current of 70 µA — the regulator's own draw stays low enough for battery-powered sensor nodes that spend most of their time in a low-power idle state. ## Temperature grade and protection for industrial bias rails An Enable pin allows the output to be gated — pulling the pin low drops the quiescent current to near zero, which is the standard method for sequencing multiple rails on a power-up or for shutting down the load during system sleep. ## SC-70-5 footprint and board integration Surface-mount assembly with Tape & Reel or Cut Tape packaging options — the reel quantity is not specified here, but the part is available in standard carrier tape for automated pick-and-place. ## Active lifecycle and RoHS3 compliance RoHS3 compliant — the /NOPB suffix indicates lead-free and halogen-free construction, meeting the current EU RoHS exemption scope without requiring an exemption certificate.","metaTitle":"LP5951MGX-2.5/NOPB LDO, 150mA, 2.5V Fixed, SC-70-5","metaDescription":"Texas Instruments LP5951MGX-2.5/NOPB LDO regulator, 150mA output, 2.5V fixed, 55µA Iq, PSRR 60dB-50dB, SC-70-5.
