For a 5 V rail fed from a 5.5 V or 6 V bus, that headroom is tight; you need a clean input above 5.22 V to hold regulation. PSRR is 63 dB at 1 kHz, which attenuates 1 mV of input ripple to roughly 0.7 µV at the output. That matters when this LDO feeds a noise-sensitive load like an ADC reference or an audio codec. ## Quiescent current and supply budget At 50 mA load, the efficiency is dominated by the dropout voltage, not the Iq — but in a standby or always-on rail, the 95 µA Iq keeps the battery drain low.","metaTitle":"LP2980IM5X-5.0/NOPB LDO Regulator, 5 V Fixed, 50 mA","metaDescription":"Texas Instruments LP2980IM5X-5.0/NOPB is a 50 mA fixed 5 V LDO in SOT-23-5.
