MCP1804T-C002I/OT: A 150mA CMOS Low-Dropout (LDO) Voltage Regulator from Microchip

In the realm of power management, efficiency and stability are paramount. The MCP1804T-C002I/OT from Microchip Technology stands out as a robust and highly efficient solution for applications requiring a clean, stable voltage supply. This 150mA CMOS Low-Dropout (LDO) Voltage Regulator is engineered to deliver exceptional performance with minimal power loss, making it an ideal choice for battery-powered and space-constrained devices.

One of the most significant advantages of the MCP1804T-C002I/OT is its extremely low dropout voltage. At a mere 178mV typical at 150mA load, this LDO can maintain regulation even when the input voltage is only marginally higher than the output. This characteristic is crucial for maximizing battery life, as it allows the system to operate effectively until the battery is nearly depleted. The device offers a fixed 2.0V output voltage, providing a reliable reference for low-power microcontrollers, sensors, and other critical components.

Constructed with a CMOS process, this regulator features very low quiescent current, typically drawing only 30 µA during operation. This minimal self-consumption ensures that very little energy is wasted, which is a vital attribute for always-on or standby applications. Furthermore, the MCP1804T-C002I/OT boasts excellent line and load regulation, ensuring a stable output despite fluctuations in input voltage or changes in the current drawn by the load.

The device is designed with a suite of built-in protection features, including current limit and thermal shutdown. These safeguards protect the regulator and the downstream circuitry from damage due to fault conditions, enhancing the overall reliability of the end product. Housed in a tiny SOT-23-5 package, it offers a compelling combination of performance and a minimal PCB footprint.

Typical applications span a wide range, including:

Battery-powered equipment

Portable medical devices

IoT sensors and modules

Portable consumer electronics

Power management for microcontrollers
