Product Description
Microchip MCP1804T-5002I/MB is a Low Dropout (LDO) voltage regulator designed for efficient power management in electronic circuits. It supports an input voltage range from 2.0 V up to 28 V and delivers a maximum output current of 150 mA. The device’s compact SOT-89 3-pin surface mount package with dimensions 4.6 mm (L) x 2.6 mm (W) x 1.6 mm (H) enables space-saving designs.
It features a very low quiescent current of 50 μA, making it suitable for battery-powered and low power applications. The regulator requires only 1 μF output capacitance to maintain stable operation, simplifying circuit design. Its current foldback protection enhances device reliability by limiting current under fault conditions.
The MCP1804T-5002I/MB includes a shutdown pin to reduce the supply current to a minimal 0.01 μA typical value for power-saving modes. It exhibits a high power supply rejection ratio (PSRR) of 50 dB at 1 kHz, ensuring stable output voltage against input supply noise.
With an input voltage maximum of 28 V and operating temperature up to 85 °C, this regulator is suitable for a variety of industrial, automotive (non-automotive standard), and consumer electronic applications requiring stable and efficient low dropout voltage regulation.
Operates over wide input voltage range of 2.0 V to 28 V. Provides up to 150 mA regulated output current. Low dropout voltage of 260 mV typical at 20 mA load current. Low quiescent current of 50 μA for power-efficient operation.
Current foldback protection improves device robustness. Shutdown feature reduces supply current to 0.01 μA (typical). High PSRR of 50 dB at 1 kHz frequency. Compact SOT-89 package for surface mount applications.
This Microchip voltage regulator is ideal for use in industrial power management IC applications, embedded systems, and consumer electronics. Its compact size and low power consumption optimize circuit space and battery life. For comprehensive product design, consult technical documents and application notes provided by Microchip to facilitate system integration.
