LR8 - Linear Regulator

General Description

LR8 is a high-voltage, low-output current, adjustable linear regulator.

This regulator has a wide operating input voltage range of 13.2-450V.

The output voltage can be adjusted from 1.20-438V, provided that the input voltage is at least 12V greater than the output voltage.

Key Features

  • 13.2-450V Input Voltage Range.
  • Adjustable 1.20-438V Output Regulation.
  • 5% Output Voltage Tolerance.
  • Output Current Limiting.
  • 10 µA Typical ADJ Current.
  • Internal Junction Temperature Limiting.
