The Microchip Technology MCP1811AT-033-HCA is a fixed 3.3V positive linear voltage regulator designed for applications requiring low quiescent current and high power supply rejection ratio (PSRR). This device delivers a stable 150mA output with a typical dropout voltage of 0.6V at 150mA. Key features include an enable pin for control, over-current, over-temperature, and short-circuit protection. The quiescent current is a mere 500 nA, with a supply current of 110 µA maximum. With an input voltage range up to 5.5V, it is suitable for battery-powered devices and portable electronics. The regulator's performance is characterized by a 50dB PSRR at 1kHz. Supplied in a compact 4-UDFN (1x1) package on tape and reel, the MCP1811AT-033-HCA is ideal for space-constrained designs in industries such as consumer electronics, industrial automation, and automotive.
