The Onsemi LP2951ACD-3.3R is a micropower, low-dropout (LDO) voltage regulator specifically configured for a fixed 3.3V output. It delivers a stable 100mA output current while maintaining regulation even with minimal input-output voltage differentials. Housed in an 8-pin SOIC SMD package, this device offers a compact footprint suitable for space-constrained applications. Its low quiescent current (typically 75µA) makes it ideal for battery-powered devices and energy-sensitive systems. The LP2951ACD-3.3R provides excellent line and load regulation, ensuring consistent performance across varying input voltages and load conditions. Its internal short-circuit and over-temperature protection enhances robustness and prevents damage. The operating temperature range spans from –40°C to 125°C, allowing for reliable operation in harsh environments. Common uses include powering microcontrollers, sensors, and other low-power digital circuits in portable devices and instrumentation. The regulator’s error flag output simplifies system monitoring and fault detection.
