The MCP1825S-1202E/AB is a fixed 1.2V LDO regulator from Microchip Technology, capable of delivering 500mA. Housed in a TO-220-3 package, it offers excellent thermal dissipation for continuous operation. With a dropout of 0.35V and quiescent current of 220 μA, it balances efficiency and performance for industrial and automotive applications.
- High Current Capacity: 500mA supports multiple digital loads from a single regulator.
- Low Dropout: 0.35V at full load maximizes headroom for low input voltages.
- Thermally Efficient: TO-220-3 package allows heatsink attachment for high-power dissipation.
- Stable Regulation: 60dB PSRR at 100Hz rejects power-line ripple.
