Microchip Low Dropout Voltage Regulator 2.0V-28V Input, 150mA, Positive Polarity, Surface Mount SOT-223 MCP1804T-C002I/DB

Microchip MCP1804T-C002I/DB is a low dropout (LDO) linear voltage regulator designed to deliver up to 150 mA of continuous current while operating from an input voltage range of 2.0 V to 28 V. This regulator maintains a stable and accurate output voltage with a typical accuracy of ±2 percent. It features a low quiescent current of approximately 50 μA, making it suitable for low-power applications in industrial, electronic, and embedded systems.

This device uses a compact SOT-223 surface mount package with four pins, allowing simple integration into printed circuit boards where space is limited. The low dropout voltage of 260 mV at a 20 mA load enables efficient regulation even at voltage inputs close to the output level.

The MCP1804 incorporates current limit protection with foldback to safeguard the device under overload or short circuit conditions. Furthermore, its shutdown pin allows the device to enter a very low current state of 0.01 μA, enhancing power savings when regulation is not required.

Thanks to its high power supply rejection ratio (PSRR) of 50 dB at 1 kHz, the regulator effectively filters out input voltage noise, ideal for sensitive analog and digital circuits. Only a minimal ceramic output capacitor of 1 μF is needed for output voltage stability, simplifying the design.

Typical applications include power management in telecommunications, battery-powered devices, instrumentation, consumer electronics, and automotive systems that do not require automotive certification. Its robust operating temperature up to 85°C ensures reliability in industrial environments.

Operates with a low quiescent current of 50 microamps for efficient power use. Provides a low dropout voltage of 260 millivolts at 20 mA load for enhanced regulation. Capable of output voltage accuracy within ±2 percent ensuring stable output.

Features current foldback for protection against overload conditions. Requires only 1 microfarad output capacitance for stabilization. Surface mount SOT-223 package with 4 pins for easy PCB integration. Maximum operating temperature of 85 degrees Celsius suitable for various environments.

High Power Supply Rejection Ratio (PSRR) of 50 dB at 1 kHz reduces noise in sensitive applications. Shutdown pin functionality reducing power consumption further during inactive states.
