ONSEMI LP2951CDR2G Adjustable LDO Voltage Regulator 100mA SOIC-8
Adjustable LDO regulator from ONSEMI, 2.25V-30V input, 100mA output, SOIC-8 package for industrial use.
The ONSEMI LP2951CDR2G is a micro-power voltage regulator engineered to maintain precise regulation with an extremely low input-to-output voltage differential. Designed for efficiency, it features a very low quiescent bias current of just 75μA while delivering output currents exceeding 100mA. Internal current and thermal limiting protect the device under fault conditions.
This regulator stands out with three advanced features. The error output signals external circuitry when the regulator falls out of regulation, doubling as a microprocessor power-ON reset. The output voltage can be preset to 5V, 3.3V, or 3V, or programmed from 1.25V to 29V using the pinned-out resistor divider and feedback input. A shutdown input allows logic-level control to turn the output on or off, conserving power when needed.
The LP2951CDR2G is packaged in a compact SOIC-8, rated for operation from -40°C to 125°C. It is ideal for battery-powered industrial equipment, computers, peripherals, and consumer electronics, where extended battery life is critical. The device ensures extremely tight line and load regulation, making it a reliable choice for precise voltage applications.
