For an analog front-end or sensor supply, this attenuation floor keeps 120 Hz ripple from coupling into the output — a 73 dB rejection at 120 Hz means a 100 mVpp input ripple is reduced to roughly 22 µVpp at the output. ## Package, temperature grade, and board-fit Rated for operation from -40°C to 125°C, this LDO suits industrial and automotive environments where the ambient temperature under the hood or inside a control cabinet can exceed 85°C. The wide temperature range, combined with the 1.5 A output, makes it a candidate for powering 5 V logic, sensor rails, or microcontroller analog supplies in thermally demanding locations. ## Protection features and quiescent draw The quiescent current (Iq) is 3 mA typical, and the maximum supply current is 10 mA, so the regulator's own consumption is modest relative to the 1.5 A load capability. An enable control feature allows the output to be gated on/off via a logic-level pin, useful for sequencing multiple rails or reducing system power in standby modes.","metaTitle":"LP3852EMP-5.0/NOPB Texas Instruments LDO, 5V Fixed, 1.5A","metaDescription":"Texas Instruments LP3852EMP-5.0/NOPB LDO regulator, 5V fixed output, 1.5A, 0.44V dropout, 73dB PSRR at 120Hz, -40 to 125°C, SOT-223-5.
