The LP2951CM-3.3/NOPB from TI is a 100mA micropower LDO with 3.3V fixed output, 60V max input, and error flag output in SOIC-8 for battery-powered and high-voltage industrial applications.

The LP2951CM-3.3/NOPB is a 3.3V 100mA micropower LDO from Texas Instruments in SOIC-8, with 60V maximum input voltage and 380mV dropout at 100mA. The device is the 3.3V fixed version of the classic LP2951, which was one of the first LDO regulators to achieve extremely low quiescent current: 75uA at 100mA load and 120uA at no load (the quiescent current is relatively flat over load, unlike standard LDOs where Iq increases with load). The PNP pass transistor architecture allows the low dropout voltage: at 100mA, the dropout is only 380mV, meaning VIN can be as low as 3.68V while maintaining 3.3V output. The SENSE pin allows remote sensing: the voltage at the load (not at the regulator output) is fed back, compensating for PCB trace resistance. The ERROR flag provides an early warning when VOUT drops below approximately 95% of the target (3.135V for 3.3V output), useful for MCU brownout detection. The BYPASS pin connects to the internal 1.235V bandgap reference; a 0.01uF capacitor on this pin reduces output noise to 30uVrms (10Hz-100kHz). The shutdown (SD) pin reduces supply current to 0.5uA, critical for battery-powered devices. The device is stable with any output capacitor >=1uF (including ceramic), unlike older LDOs that required specific ESR ranges. The TAP pin provides access to the internal 1.235V reference for the adjustable version. The -CM-3.3 suffix specifies SOIC-8, 3.3V fixed output. Applications include: automotive battery-powered systems, 4-20mA loop regulators, and industrial sensor power.
