MIC2954-07YM-TR

MIC2954-07YM-TR Description

The MIC2954-07YM-TR from Microchip Technology is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision power management in demanding applications. This positive-adjustable (or fixed 5V output) regulator delivers up to 250mA of output current with an ultra-low dropout voltage of 0.6V at full load, ensuring efficient operation even with tight input-to-output differentials. The device supports a wide input voltage range (up to 30V) and offers an adjustable output from 1.24V to 29V, making it versatile for various power supply designs. Packaged in an 8-pin SOIC and available in tape & reel (TR), it is optimized for surface-mount assembly and complies with RoHS3 and REACH environmental standards.

MIC2954-07YM-TR Features

• Low Dropout Voltage: Only 0.6V @ 250mA maximizes efficiency in battery-powered systems.
• Wide Input Range: 30V max input tolerance suits automotive, industrial, and telecom applications.
• Adjustable/Fixed Output: Configurable from 1.24V to 29V or fixed 5V for design flexibility.
