The Microchip MCP1826ST-1802E/EB is a fixed 1.8V low dropout regulator capable of sourcing 1A with an ultra-low dropout of 0.4V. Its 220 μA quiescent current and 60dB PSRR at 100Hz make it suitable for high-current, noise-sensitive applications. The DDPAK-3 package ensures excellent thermal performance.
- 1A Output Current: Supports high-power digital loads without external pass transistors.
- Ultra-Low Dropout (0.4V): Maximizes efficiency when operating from 3.3V or 5V supplies.
- 60dB PSRR at 100Hz: Excellent low-frequency noise rejection for audio and precision circuits.
- DDPAK-3 Package: Robust thermal dissipation for continuous 1A operation.
