It is built for surface-mount assembly in a TO-261-5 (SOT-223) package, with an operating junction temperature range of -40°C to 125°C that covers automotive under-hood and industrial motor-drive environments. The 55 dB PSRR at 120 Hz gives it a clean post-rectifier ripple rejection profile for noise-sensitive analog supplies. ## Thermal and protection profile Over-temperature shutdown is built in, but no current-limit or reverse-current protection is listed. The junction temperature rating to 125°C means the part can sit in a warm enclosure or near a hot power stage as long as the PCB copper area keeps the die within limits. Quiescent supply current maxes at 100 µA — low enough for always-on rails in battery-backed equipment, though not a true ultra-low-Iq part. ## Lifecycle and sourcing posture The LP38692MP-1.8 carries an active lifecycle status, so no last-time-buy clock is running. It is RoHS non-compliant per the listing — verify your assembly line's exemption requirements if you need a lead-free process.","metaTitle":"LP38692MP-1.8 LDO Regulator, 1.8V Fixed Output, 1A, SOT-223","metaDescription":"LP38692MP-1.8 is a 1.8V fixed-output LDO rated for 1A with 55dB PSRR at 120Hz and -40°C to 125°C range.
