Because the output voltage is set internally, the BOM saves two feedback resistors and the associated PCB trace — the 5V rail is non-negotiable and ready to power 5V logic, analog front-ends, or sensor supplies. Below that headroom, the output follows the input minus the dropout — a consideration when the supply is a battery nearing end-of-discharge or a loosely regulated bus. ## 65 dB PSRR — how clean does the output stay? Power-supply rejection ratio is 65 dB at 1 kHz — that attenuates a 100 mV ripple on the input to roughly 56 µV at the output at that frequency. If the upstream supply is a switching regulator switching at 500 kHz, the PSRR at that frequency will be lower; the 65 dB figure at 1 kHz tells you the mid-band rejection is solid, but the high-frequency attenuation depends on the output capacitor's ESR and the LDO's control-loop bandwidth. Quiescent current is 150 µA typical — the LDO's own draw stays low enough for always-on rails in battery-powered equipment, but it is not an ultra-low-Iq part. The maximum supply current is 3.7 mA, which includes the output drive when the LDO is not in shutdown. ## Temperature grade and protection — where this LDO fits An Enable pin (active-high logic) allows the regulator to be gated by a GPIO or a power-good signal from another rail, simplifying power-up sequencing. ## Active lifecycle — but RoHS non-compliant No cross-reference or second-source is recorded; the fixed 5V output and 8-SOIC package define the fit.","metaTitle":"Texas Instruments LP2986IMX-5.0 LDO, 5V Fixed, 200mA, 8-SOIC","metaDescription":"Texas Instruments LP2986IMX-5.0 fixed 5V LDO regulator, 200mA output, 65dB PSRR at 1kHz, 0.35V dropout.
