Product Description

The LP2954AIMX/NOPB is a low-dropout (LDO) voltage regulator from Texas Instruments' LP2954 series, designed for precise voltage regulation in demanding applications. This fixed or adjustable output regulator supports a wide input voltage range of 4.5V to 30V, delivering up to 250mA of output current. The adjustable version allows users to set the output voltage between 1.24V and 29V via an external resistor divider. With a typical dropout voltage of 380mV at 250mA, it ensures efficient operation in low-voltage scenarios. Operating across an industrial temperature range (-40°C to +125°C), the LP2954AIMX/NOPB integrates features like current limiting, thermal shutdown, and error flag detection for fault monitoring. It is widely used in automotive systems, industrial controls, and portable electronics due to its robust design, low quiescent current (75µA typical), and stability with low-ESR capacitors. While its output current may be insufficient for high-power applications, its reliability, minimal external components, and versatility make it a preferred choice for precision power management.
