MIC94310-4YM5-T5 – MICREL

The MIC94310-4YM5-T5, manufactured by MICREL, is a low-dropout (LDO) linear regulator integrated circuit designed for point-of-load regulation in portable and battery-powered applications. This device provides a fixed 1.2V output voltage with a guaranteed output current of 200mA. It features a low quiescent current, typically in the microampere range, to maximize battery life. The regulator is internally compensated for stability with ceramic output capacitors. Protection features include overcurrent limiting and thermal shutdown, safeguarding the device and downstream circuitry from fault conditions. The MIC94310-4YM5-T5 is packaged in a space-saving SOT23-5 surface-mount package, making it suitable for high-density PCB layouts. Its input voltage range is optimized for single-cell lithium-ion battery applications and other low-voltage power sources.
