Quiescent current is 55 µA typical, with a maximum supply current of 100 µA — low enough for always-on rails in battery-backed or standby circuits where the regulator's own draw must not dominate the system budget. ## Industrial temperature grade and thermal management The SOT-223-5 package (TO-261-5 equivalent) has an exposed pad on the bottom — the primary thermal path for the 1 A output. Board layout must connect this pad to a copper plane to keep the junction temperature within the operating range at full load. Built-in over-temperature protection shuts the die down under sustained overload or high ambient; the part cycles off and on until the fault clears. No over-current or reverse-voltage protection is integrated — external circuitry is required if those failure modes are expected. ## PSRR and ripple rejection in signal-chain rails Power-supply rejection ratio is 55 dB at 120 Hz — this is the line-frequency ripple rejection figure. Above the crossover frequency the PSRR rolls off; upstream switching noise above a few hundred kHz will pass through unless filtered ahead of the LDO.","metaTitle":"LP38692MPX-5.0/NOPB Texas Instruments LDO, 5V Fixed, 1A","metaDescription":"Texas Instruments LP38692MPX-5.0/NOPB linear regulator, 5V fixed output, 1A, 55dB PSRR at 120Hz, SOT-223-5.

This means the regulator attenuates line-frequency ripple from a rectified AC input by a factor of about 560×. For a 5 V rail feeding an analog or RF signal chain, this rejection keeps the supply clean enough to avoid injecting hum into the signal path."},{"question":"What compliance documentation does Texas Instruments provide for LP38692MPX-5.0/NOPB?","answer":"Texas Instruments provides ROHS3 compliance certification for the LP38692MPX-5.0/NOPB.
