MIC5249-1.5YMM Description

Short technical summary and product information.

The MIC5249-1.5YMM is a high-performance, 300mA CMOS voltage regulator designed by Microchip Technology (formerly Micrel). This LDO regulator provides a stable 1.5V output with excellent accuracy and low dropout voltage, making it suitable for noise-critical, battery-powered applications.

 

Key electrical specifications include a typical dropout voltage of 340mV at 300mA, 1% initial accuracy, and a low quiescent current of 85µA. It features a high Power Supply Rejection Ratio (PSRR) of 65dB at 120Hz, and is stable with ceramic output capacitors. Protection features include current limit and thermal shutdown.

 

The device is designed for applications such as cellular phones and PDAs. It comes in a compact 8-MSOP package, suitable for space-constrained designs. The regulator also includes features like a power-on reset (POR) delay and a noise reduction pin for filtering output noise.

 

This regulator operates over a temperature range of -40°C to 125°C and is surface-mount compatible. Its design prioritizes efficiency and performance in portable electronic devices.
