Microchip Low Dropout Voltage Regulator 28V Input, 150mA Output, SOT-23 5-Pin MCP1804T-3302I/OT

Microchip MCP1804T-3302I/OT is a low dropout (LDO) voltage regulator designed for precision power management in electronic circuits. It operates efficiently over an input voltage range of 2.0 V to 28 V, delivering a maximum output current of 150 mA, making it suitable for low power embedded and portable devices.

The device consumes a quiescent current of only 50 μA, reducing power wastage during operation, and features an ultra-low shutdown current of 0.01 μA to extend battery life in portable applications. Its low dropout voltage of 260 mV at 20 mA output ensures stable output voltage regulation with minimal voltage loss.

The MCP1804T-3302I/OT comes in a small surface mount SOT-23 5-pin package with dimensions of 3.1 mm length, 1.8 mm width, and 1.3 mm height, allowing high-density PCB layouts. Its positive polarity and current foldback protection ensure enhanced safety and device longevity.

The regulator features a high power supply rejection ratio (PSRR) of 50 dB typical at 1 kHz, minimizing output noise and ripple, critical for audio, communication, and precision measurement devices. Stability is achieved with a minimal ceramic output capacitor of 1 μF, simplifying system design and reducing overall component count.

Additional features include a dedicated shutdown pin to manually enable or disable the output, ensuring flexible circuit control. The device is suitable for a wide range of industrial, laboratory, computer, and commercial electronic applications requiring regulated power delivery in a compact footprint.

The regulator offers up to 150 mA output current for moderate power applications. Low quiescent current of 50 μA minimizes power consumption during operation. Compact SOT-23 5-pin surface mount package facilitates compact designs.

Wide input voltage range from 2.0 V to 28 V supports varied power sources. Current limit protection with current foldback enhances reliability and safety. Stable output with minimal 1 μF ceramic capacitor requirements. High PSRR reduces output noise and improves performance.

Shutdown pin provides external control for power saving.
