The 2.5 mA maximum supply current covers the internal bias and protection circuits. PSRR is 45 dB at 1 kHz — this attenuates 100 mV of 1 kHz ripple on the input to roughly 560 µV at the output. For upstream switching noise above 100 kHz, expect less rejection; the LDO alone won't clean a noisy buck converter's output without a post-filter. An enable pin lets the system pull the output to zero and drop the quiescent draw to near-zero in standby. ## Active production — RoHS non-compliant, legacy BOMs only RoHS compliance is listed as non-compliant. This part is intended for legacy BOMs that do not require RoHS conformance, or for applications with an explicit exemption. For new designs requiring RoHS compliance, a tin-lead-free equivalent in the same family should be selected. The SOT-23-5 package is widely stocked across the supply chain, but the RoHS non-compliant status narrows the pool of ready inventory. Lead time and lot traceability are provided with each RFQ response.","metaTitle":"LP2985IM5X-3.0 LDO Regulator, 3.0V Fixed, 150mA, SOT-23-5","metaDescription":"Texas Instruments LP2985IM5X-3.0 LDO regulator, 3.0V fixed output, 150mA, 0.58V dropout, 45dB PSRR, SOT-23-5.
