Overview

Features and Benefits

  • NOT RECOMMENDED FOR NEW DESIGNS
    Contact Analog Devices for Potential Replacement
  • Guaranteed 1% Initial Voltage Tolerance
  • Guaranteed 0.015%/V Line Regulation
  • Guaranteed 0.02%/W Thermal Regulation
  • 100% Thermal Limit Burn-In

Product Details

The LT1033 negative adjustable regulator will deliver up to 3A output current over an output voltage range of –1.2V to –32V, with better line and load regulation and a maximum output voltage error of 1%.

The LT1033 is easy to use and difficult to damage. Internal current and power limiting as well as true thermal limiting prevents device damage due to overloads or shorts, even if the regulator is not fastened to a heat sink.

Maximum reliability is attained with advanced processing techniques combined with a 100% burn-in in the thermal limit mode. This assures that all device protection circuits are working and eliminates field failures experienced with other regulators that receive only standard electrical testing.

Applications

  • Adjustable Power Supplies
  • System Power Supplies
  • Precision Voltage/Current Regulators
  • On-Card Regulators
