Quality Control: Learn More
The Microchip Technology MCP1811AT-018-HCA is a fixed output voltage linear regulator IC. This device provides a stable 1.8V output with a maximum current capability of 150mA. Key features include a low quiescent current of 500 nA and a low input current of 110 µA, making it suitable for battery-powered applications. The regulator offers robust protection against over current, over temperature, and short circuit conditions. With a maximum input voltage of 5.5V and a low dropout voltage of 0.6V at 150mA, it maintains regulation efficiently. The device is supplied in a compact 4-UDFN (1x1) exposed pad package, designed for surface mounting. Its high power supply rejection ratio (PSRR) of 50dB at 1kHz and an enable pin for control further enhance its utility in automotive, industrial, and consumer electronics. This component operates within a temperature range of -40°C to 85°C.
