Product Description
Microchip MCP1804T-A002I/OT is a high-performance Low Dropout (LDO) Voltage Regulator designed for electronic components requiring stable power management. It supports an input voltage range from 2.0 V to 28 V and delivers up to 150 mA of regulated output current.
This device features exceptionally low quiescent current of 50 μA, making it ideal for battery-powered and low-power applications. Its low dropout voltage of 260 mV at 20 mA ensures efficient voltage regulation even near the supply limits.
The shutdown pin allows for ultra-low shutdown current of just 0.01 μA, making system power management more effective. Only 1 μF of ceramic output capacitance is needed to ensure output stability, simplifying circuit design.
To protect against overcurrent conditions, the MCP1804 incorporates current limit protection with a Current Foldback feature. The high Power Supply Rejection Ratio (PSRR) of 50 dB at 1 kHz reduces supply noise impact, improving system reliability.
Encased in a compact SOT-23 5-pin surface mount package measuring 3.1 mm long, 1.8 mm wide, and 1.3 mm high, the MCP1804 integrates easily into compact electronic designs. The device operates reliably up to a temperature of 85°C, suitable for various industrial and consumer electronics environments.
Operates from 2.0 V to 28 V input voltage range. Supplies up to 150 mA regulated output current. Low dropout voltage of 260 mV at 20 mA typical. 50 μA typical quiescent current. Shutdown pin with 0.01 μA typical shutdown current.
Stable operation with 1 μF output capacitance. Current limit protection with Current Foldback. High PSRR of 50 dB at 1 kHz. Compact SOT-23 5-pin surface mount package. Operating temperature up to 85°C.
This voltage regulator is suitable for industrial, computing, telecommunications, and automotive power management tasks where compact size and power efficiency are critical. Its features meet the demanding needs of modern electronic systems requiring reliable, low-noise voltage regulation.
