The 0.22 V max dropout at full load means the input can sit as low as 1.45 V above the set output and still hold regulation — useful when the pre-regulator rail is already tight. ## Output voltage range and setting resistors The 16 V maximum input gives headroom for 12 V or 15 V rails. The Enable pin allows the output to be gated by a logic signal, saving quiescent draw when the downstream load is idle. ## Temperature grade and protection suite On-chip protection includes over-current, over-temperature, and short-circuit — the regulator survives a sustained output short without damage, though the die temperature will cycle the thermal limit. ## Package and footprint — SOT-23-5 Supplied in a SOT-23-5 package, also described as SC-74A / SOT-753. The 5-pin footprint is standard for small LDOs; the Enable pin on pin 3 and the adjustable feedback on pin 4 match the LP2980 family pinout. ## Quiescent current and always-on budget The 95 µA quiescent current is moderate for a 50 mA LDO — not the lowest in class, but low enough for always-on domains where the regulator stays powered while the load sleeps. The 1.2 mA maximum supply current includes the pass-element drive; at light loads the actual draw sits closer to the Iq figure.","metaTitle":"LP2980IM5X-ADJ/NOPB LDO Regulator, Adjustable, 50 mA","metaDescription":"Texas Instruments LP2980IM5X-ADJ/NOPB adjustable LDO, 50 mA output, 63 dB PSRR at 1 kHz, 0.22 V dropout max.
