MIC5323-1.8YD5-TR

MIC5323-1.8YD5-TR Description

The MIC5323-1.8YD5-TR is a high-performance, fixed-output linear voltage regulator from Microchip Technology, designed to deliver a stable 1.8V output at up to 300mA of continuous current. With a wide input voltage range of up to 5.5V, this regulator is optimized for low-dropout operation, featuring a maximum dropout voltage of 0.22V at full load. Its ultra-low quiescent current (150 µA) and high PSRR (80dB @ 1kHz) make it ideal for noise-sensitive applications. Packaged in a compact TSOT23-5 form factor and available in tape-and-reel (TR) packaging, it is well-suited for space-constrained designs.
