Microchip Low Dropout Voltage Regulator 28V 150mA Surface Mount SOT-223 4-Pin MCP1804T-C002I/DB

Microchip MCP1804T-C002I/DB is a low dropout (LDO) voltage regulator designed to provide precise and efficient power regulation in electronic circuits. It operates within an input voltage range of 2.0 V to 28 V and delivers a continuous output current up to 150 mA. Packaged in a compact surface-mount SOT-223 4-pin form factor, this regulator is ideal for space-constrained applications requiring reliable voltage regulation with minimal power loss.

With a typical dropout voltage of only 260 mV at a 20 mA load, the MCP1804 offers efficient performance suitable for battery-powered and power-sensitive devices. The regulator's low quiescent current of 50 μA and almost negligible shutdown current of 0.01 μA contribute to extended battery life and lower overall power consumption.

The device is stable with ceramic output capacitors as low as 1 μF, simplifying design and reducing the bill of materials. It features current limit protection with current foldback to prevent damage under fault conditions. The regulator also provides a high power supply rejection ratio (PSRR) of 50 dB at 1 kHz, ensuring clean and stable output voltage under noisy input conditions.

Measuring 6.7 mm in length, 3.7 mm in width, and 1.7 mm in height, the SOT-223 surface mount package facilitates easy PCB assembly and integration into automated manufacturing processes. Its operating temperature range up to 85°C makes it suitable for a variety of industrial, electronic, and consumer applications.

Common uses include voltage regulation in power management modules, portable electronics, embedded systems, and instrumentation. This IC is an excellent choice for engineers seeking a compact, efficient, and reliable linear Voltage Regulator solution.
