The 0.27V maximum dropout at full load means the input supply needs only 3.27V to keep the output in regulation — useful when the pre-regulator rail sags under transient load. The 65dB PSRR at 120Hz tells you the regulator attenuates rectified line ripple by a factor of roughly 1800 — a clean 3V rail for analog front-ends or reference supplies that sit downstream of a noisy DC-DC converter. ## Industrial temperature range and protection The quiescent current is 500 µA typical, with a maximum supply current of 800 µA — the regulator's own draw stays low enough that it won't dominate the thermal budget in a 250mA design. Built-in over-current and over-temperature protection means the part folds back or shuts down before the junction exceeds the safe operating area. No external crowbar or PTC needed for a basic fault-tolerant rail. The enable control pin lets the system processor gate the 3V rail during sleep modes — pulling the pin low drops the output and cuts the quiescent current to near zero, which matters for battery-backed or always-on supplies. ## SOT-23-5 footprint and sourcing posture Housed in the SC-74A / SOT-753 package, the part uses the standard SOT-23-5 footprint — 5 pins with 0.95mm pitch. The small body (roughly 3mm x 3mm) fits tight mixed-signal layouts where the LDO sits near the analog load to keep the sense trace short.","metaTitle":"Texas Instruments REG102NA-3/250 LDO Regulator, 3V Fixed","metaDescription":"Texas Instruments REG102NA-3/250 LDO, 3V fixed output, 250mA, 65dB PSRR at 120Hz, SOT-23-5.
