Overview

The ATL431 and ATL432 are three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and industrial temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors.

  • 1 Adjustable Regulated Output of 2.5 V to 36 V
  • Very-Low Operating Current - IKA(min) = 35 µA (Max) - IREF = 150 nA (Max)
  • Internally Compensated for Stability - Stable With No Capacitive Load
  • Reference Voltage Tolerances at 25°C - 0.5% for B Grade - 1% for A Grade
  • Typical Temperature Drift - 5 mV (-40°C to +85°C); I Version - 6 mV (-40°C to +125°C); Q Version
  • Extended Cathode Current Range 35 µA to 100 mA
  • Low Output Impedance of 0.3 Ω (Max)
