Microchip Low Dropout Voltage Regulator 28V 3-Pin SOT-89 MCP1804T-3302I/MB

Microchip MCP1804T-3302I/MB is a high-performance Low Dropout (LDO) voltage regulator designed for stable power regulation in a compact surface mount SOT-89 package. It accepts an input voltage range from 2.0 V to 28.0 V, suitable for various industrial and consumer electronic applications requiring regulated output with low noise and high efficiency.

This device delivers a maximum output current of 150 mA with a typical dropout voltage of just 260 mV at 20 mA load, ensuring minimal power loss and better battery life in portable devices. The regulator features a very low quiescent current of 50 μA during operation and an ultra-low shutdown current of 0.01 μA to optimize power usage under different operating states.

The MCP1804T-3302I/MB maintains output voltage accuracy within ±2% and requires minimal external components, needing only a 1 μF ceramic capacitor to stabilize the output voltage. It provides current limit protection with current foldback functionality to prevent damage under short circuits or fault conditions.

Its high power supply rejection ratio (PSRR) of 50 dB at 1 kHz frequency effectively reduces the noise and ripple from input power sources, making it ideal for noise-sensitive electronic circuits. The compact 3-pin SOT-89 package dimensions of 4.6 mm length, 2.6 mm width, and 1.6 mm height allow flexible PCB layouts and space-saving designs.

Common industrial, laboratory, and automotive use cases involve powering microcontrollers, sensors, and other sensitive electronics requiring reliable, low-noise voltage regulation. With a maximum operating temperature of 85°C, it is suitable for a range of environmental conditions.
