The fixed output eliminates the need for external resistor dividers, saving board space. ## Dropout and PSRR — what they mean for your rail The 45dB PSRR at 1kHz tells you how well the LDO rejects input ripple at that frequency. For a switching regulator feeding this LDO, if the switcher's fundamental or harmonics land near 1kHz, the attenuation may be marginal — a second LC stage or a higher-PSRR LDO might be needed for sensitive analog or RF loads. ## Quiescent current and always-on budget The 95 µA quiescent current is the current the LDO consumes just to stay alive, regardless of load. ## Package and footprint The SOT-23-5 package is a standard 5-pin surface-mount footprint, shared with many other LDOs and logic devices. The enable pin is active-high; leave it floating or tie to Vin if not used. ## Lifecycle and sourcing posture The LP2985AIM5-2.5/NOPB is listed as Active with RoHS3 compliance. There is no end-of-life notice or last-time-buy window. For BOM planning, no immediate lifecycle risk exists, and the NOPB suffix confirms lead-free / RoHS3-compliant construction.","metaTitle":"LP2985AIM5-2.5/NOPB LDO Regulator, 2.5V Fixed, 150mA","metaDescription":"TI LP2985AIM5-2.5/NOPB is a 2.5V fixed-output LDO rated for 150mA, 45dB PSRR at 1kHz, 95µA Iq.
