50 mA fixed 3.2 V LDO — PSRR and dropout profile
The LP2980IM5X-3.2/NOPB fixed 3.2 V output LDO delivers 63 dB PSRR at 1 kHz and accepts up to 16 V input. Maximum dropout is 0.22 V at 50 mA. Quiescent current is 95 µA typical; maximum supply current is 1.2 mA.
Industrial temperature grade and protection set
The protection block includes over-current, over-temperature, and short-circuit — enough to survive a bench fault or a hot reflow without latching up. The enable control feature lets a GPIO or supervisor IC gate the output, which is useful for sequencing multiple rails or shutting down a peripheral in sleep mode. The fixed 3.2 V output is less common than 3.3 V — check that your load's tolerance band accepts the 3.2 V nominal before committing the BOM.
