LP2951-50DRGR TI Voltage Regulators - Linear, Low Drop Out (LDO)
The LP2951 is a micropower fixed/adjustable positive LDO regulator providing 100 mA output with fixed 5.0 V output (or adjustable from 1.235 V to 30 V). It operates from 2.3 V to 30 V input and features low dropout of 380 mV at 100 mA. The device includes an error flag for output voltage monitoring, a shutdown pin for power savings, and current limiting with thermal protection. Quiescent current is 75 µA typical. Packaged in 8-pin WSON (DRG), the LP2951 is ideal for battery-powered and portable instrumentation requiring low power consumption and voltage monitoring. Applications include battery-powered devices, handheld instrumentation, post-regulation for switching converters, and automotive systems requiring a low-dropout 5 V rail with logic-controlled enable and power-good monitoring.
