Microchip Voltage Regulator SOT-223 4-Pin 28V Maximum Input Voltage 150mA Output Current MCP1804T-5002I/DB

Microchip MCP1804T-5002I/DB is a high-performance Low Dropout (LDO) voltage regulator designed for efficient power management in electronic circuits. Encased in a compact SOT-223 4-pin surface mount package, this positive polarity regulator supports input voltages from 2.0 V up to 28 V and delivers a stable output current of up to 150 mA.

The regulator features an ultra-low quiescent current of 50 μA which makes it ideal for battery-powered and portable devices where energy conservation is critical. It requires only a minimal 1 μF ceramic output capacitor to ensure output stability, simplifying circuit design and reducing space.

Equipped with current limit protection including current foldback, the MCP1804 enhances device safety by preventing damage under overload conditions. Additionally, its shutdown pin allows the device to be turned off, reducing shutdown current to as low as 0.01 μA to save power during idle states.

Its high power supply rejection ratio (PSRR) of 50 dB at 1 kHz minimizes output voltage variations caused by input voltage fluctuations, ensuring reliable performance in noisy electronic environments.

This voltage regulator is engineered for broad industrial and commercial applications such as power management for microcontrollers, portable instrumentation, and general electronics systems requiring regulated power supplies within its voltage and current range. Its compact size and surface mount design facilitate integration in space-constrained printed circuit boards.

Key specifications include a maximum operating temperature of 85°C, a package dimension of approximately 6.7 mm length, 3.7 mm width, and 1.7 mm height. The MCP1804 series is a versatile solution for applications demanding low dropout voltage and efficient power regulation.

The regulator stabilizes output voltage with ±2% accuracy, suitable for precision devices. Compact SOT-223 surface mount package enables efficient assembly. Low quiescent current improves battery life in portable electronics.

Current foldback and limit provide robust overload protection. Wide input voltage range supports varied power sources. Suitable for use in industrial, laboratory, electronic component manufacturing, and power management systems.
