The 4.7V rail is less common than 3.3V or 5.0V — it typically feeds analog front-ends, sensor bias circuits, or reference supplies that need a voltage between the standard logic rails. ## Dropout and quiescent current — the battery budget Maximum dropout voltage is 0.22V at the full 50mA load, so the input rail needs at least 4.92V to maintain regulation — a Li-ion cell near its end-of-discharge (3.0V) won't cut it; this part expects a 5V bus or a higher intermediate rail. Quiescent current is 95 µA typical, and the maximum supply current (including the output load) is 1.2 mA. For always-on circuits drawing microamps, the 95 µA Iq is noticeable — a lower-Iq LDO would stretch battery life, but the 1.2 mA ceiling keeps the thermal rise modest in the SOT-23-5 at full load. ## PSRR at 1 kHz — audio-band ripple rejection PSRR is specified at 63 dB at 1 kHz, which means the output attenuates a 1 kHz ripple on the input by a factor of roughly 1400. That's adequate for cleaning up switching-regulator feedthrough in the audio band, though the rejection rolls off above a few hundred kHz — a ceramic input cap with low ESL helps keep high-frequency noise from coupling through. Texas Instruments no longer manufactures this fixed-voltage variant in production volumes. For a production line that needs this exact 4.7V rail, the independent channel is the practical path; for new designs, a currently-active LDO with a 4.7V fixed option or an adjustable-output sibling in the same footprint should be evaluated. ## Protection and temperature range Built-in protection covers over-current, over-temperature, and short-circuit events — the regulator folds back or shuts down before the die exceeds its safe junction temperature.","metaTitle":"LP2980AIM5X-4.7 LDO Regulator, 4.7V Fixed, 50mA, SOT-23-5","metaDescription":"Texas Instruments LP2980AIM5X-4.7 LDO voltage regulator, fixed 4.7V output, 50mA, 0.22V dropout, PSRR 63dB at 1kHz.
