Microchip Technology LR645LGG High-Voltage Regulator
The LR645 is a high-input voltage, low-output current linear regulator suitable for off-line SMPS and noisy input applications. It accepts voltages from 15 to 450V, providing a fixed 10V output or an adjustable output range of 8 to 12V through external resistors. Designed for start-up circuits, it minimizes power dissipation after initial power-up by drawing current only during start-up. Packages include TO-92, TO-220, SOIC, and SOT-89, supporting various current and voltage configurations. It features low quiescent current, excellent regulation, and is ideal for low-power, high-voltage power regulation and noisy environments.
