Texas Instruments LP2951ACN Voltage Regulator, 100mA, 30V

The Texas Instruments LP2951ACN/NOPB is a micropower linear voltage regulator engineered for exceptional efficiency in battery-powered and low-voltage systems. It features an extremely low quiescent current of just 75µA (typical) and a remarkably low dropout voltage—typically 40mV at light loads and 380mV at the full 100mA output. This combination minimises power waste, significantly prolonging battery life in portable devices. Notably, the quiescent current increases only slightly even when the regulator is in dropout, further conserving energy.

The regulator offers a wide input voltage range from 2.3V to 30V, making it versatile for various applications. It provides a guaranteed output current of 100mA with high accuracy, extremely tight load and line regulation, and a very low temperature coefficient for stable performance across environmental conditions. The output voltage is user-adjustable, spanning from 1.24V to 29V, offering design flexibility for precise voltage requirements.

Housed in a robust 8-pin DIP (Dual In-line Package) for through-hole mounting, this component is built for reliability and ease of integration into prototypes and finished PCB designs. Its operating temperature range of -40°C to 125°C ensures dependable function in demanding industrial, automotive, and consumer electronics environments. With its focus on low power consumption and stable regulation, the LP2951ACN is an ideal choice for power-sensitive designs where every milliamp and millivolt counts.
