Microchip Technology LR8N3G High-Voltage Linear Regulator
LR8 is a high-voltage, adjustable linear regulator suitable for industrial controls, motor controls, and power supplies. It supports input voltages from 13.2V to 450V, with adjustable output from 1.20V to 438V by external resistors. The device provides current limiting to 20mA, temperature limiting, and a stable voltage difference of 1.20V between VOUT and ADJ pins. Available in TO-243AA, TO-252, and TO-92 packages, LR8 ensures reliable operation in off-line SMPS startup circuits and high-voltage constant current sources, with built-in thermal and current protections.
