The MCP1825T-1802E/DC from Microchip Technology is a fixed 1.8V LDO regulator delivering 500mA. With a low dropout of 0.35V at full load and 220µA quiescent current, it balances efficiency and performance. The SOT-223-5 package provides excellent thermal characteristics for industrial and automotive applications.
- Low Dropout: 0.35V at 500mA reduces power loss and allows operation from lower input rails.
- High Current: 500mA supports a wide range of digital and analog loads.
- Thermal Efficiency: SOT-223 package dissipates heat effectively for reliable operation.
- Good PSRR: 60dB at 100Hz filters ripple from rectified AC supplies.
