The 1.2 mA maximum supply current includes the internal bias — no external charge pump needed. Enable control lets the system shut the regulator down when the 1.8 V rail is idle. ## Protection set and temperature range On-chip over-current, over-temperature, and short-circuit protection cover the common fault modes in a 50 mA rail.","metaTitle":"LP2980IM5-1.8/NOPB LDO Regulator, 1.8V Fixed, 50mA, SOT-23-5","metaDescription":"Texas Instruments LP2980IM5-1.8/NOPB is a 50mA fixed-output LDO regulator delivering 1.8V with 63dB PSRR at 1kHz.
