The MCP1826S-1802E/DB is a fixed 1.8V low dropout regulator from Microchip Technology, capable of delivering up to 1A of output current. With an ultra-low dropout voltage of just 0.4V at full load, it is perfect for battery-powered and low-voltage applications. The quiescent current is 220 µA, and the PSRR of 60dB at 100Hz ensures clean output for analog and RF circuits. The SOT-223-3 package offers excellent thermal performance in a compact footprint.
- 1A Output Current: High capacity for demanding digital loads.
- Ultra-Low Dropout: 0.4V at 1A enables efficient operation from low input voltages.
- Low Noise: 60dB PSRR at 100Hz for sensitive analog and RF applications.
- Compact SOT-223: Small size with good heat dissipation for space-constrained designs.
