The MIC2920A-3.3WT from Microchip Technology is a fixed 3.3V low-dropout regulator capable of 400mA output. With a dropout voltage of 0.75V at full load and a low quiescent current of 300µA, it balances efficiency and simplicity. The TO-220-3 package ensures excellent thermal dissipation for industrial and automotive applications.
- Thermal Robustness: TO-220 package dissipates heat effectively for high-current operation.
- Low Power Loss: 0.75V dropout at 400mA reduces wasted energy compared to standard regulators.
- Simple Integration: Fixed 3.3V output requires no external resistors, simplifying BOM.
- Wide Availability: Industry-standard pinout compatible with many existing designs.
