The dropout voltage is specified at 0.22 V max at the full 50 mA load. ## 63 dB PSRR at 1 kHz — noise rejection for sensitive loads The 63 dB PSRR at 1 kHz means the regulator attenuates ripple on the input by roughly 1,400× at that frequency. For an analog front-end or a PLL supply that sees 1 kHz switching noise from a DC-DC converter, this LDO cleans the rail without needing a post-filter LC stage. ## Industrial temperature range and protection set On-chip protection includes over-current, over-temperature, and short-circuit limiting. The enable pin lets a system supervisor or GPIO gate the output rail. For BOM lines that still specify this exact 3.2 V fixed-output LDO, the only sourcing path is the independent distribution market — new-old-stock or surplus inventory sourced per RFQ. The SOT-23-5 footprint is widely used across the LP2980 family and by other LDO vendors, so a pin-compatible second source may exist from manufacturers like Microchip or ON Semiconductor — but no cross-reference is recorded in the official documentation. Any alternate must be qualified against the 3.2 V fixed output and the 0.22 V max dropout at 50 mA.","metaTitle":"LP2980AIM5X-3.2/NOPB LDO Regulator, 3.2V Fixed Output, 50mA","metaDescription":"Texas Instruments LP2980AIM5X-3.2/NOPB is a 50mA fixed-output LDO regulator delivering 3.2V with 63dB PSRR at 1kHz.
