Microchip 5-Channel Low Dropout Voltage Regulator 250mA 5V SOT-223 3-Pin MCP1703

Microchip MCP1703 is a 5-Channel Low Dropout (LDO) Linear Voltage Regulator designed to provide reliable voltage regulation with low power consumption and excellent line and load regulation characteristics. Featuring a fixed 5V output voltage and capable of supplying up to 250 mA output current, it is ideal for use in a wide range of power management applications in electronics and industrial systems.

Housed in a space-efficient SOT-223 3-pin surface mount package, the MCP1703 regulator supports operation in a broad temperature range of -40°C to +125°C, making it suitable for harsh environments and automotive-related applications where stability and performance consistency are critical.

The regulator features a low quiescent current of just 2μA, minimizing power loss and improving the overall efficiency of battery-powered or energy-sensitive devices. It delivers five output channels with fixed positive polarity, facilitating ease of integration in multi-output power management circuits.

Furthermore, the device offers exceptional line regulation of 0.1 %/V and load regulation of 1 %, ensuring stable voltage output even with variations in input supply or load conditions. Its maximum input voltage rating of 16V and minimum input voltage of 2.7V broaden the range of compatible power sources.

The MCP1703 series complies with RoHS standards, ensuring adherence to environmental regulations by restricting hazardous substances. Its compact dimensions (6.5mm length, 3.5mm width, and 1.6mm height) make it suitable for compact PCB designs in consumer electronics, instrumentation, embedded systems, and power supply modules.
