Microchip Technology MCP1811BT-033-HCA is a high-performance, low quiescent current linear voltage regulator. This device provides a stable 3.3V output with a maximum output current of 150mA. The MCP1811BT-033-HCA features a low dropout voltage of 0.6V at 150mA, ensuring efficient operation even under demanding load conditions. It includes an active-low output enable pin for power sequencing and management. Protection features include over-current, over-temperature, and short-circuit protection. With a typical quiescent current of 0.5 µA and a supply current of 110 µA (max), this regulator is ideal for battery-powered applications. The device operates from an input voltage range of up to 5.5V and is housed in a compact 4-UDFN (1x1) exposed pad package, suitable for surface mount assembly. Key applications include portable electronics, IoT devices, and automotive systems. The high power supply rejection ratio (PSRR) of 50dB at 1kHz contributes to clean power delivery.
