The LT®1033 negative adjustable regulator will deliver up to 3A output current over an output voltage range of –1.2V to –32V. Linear Technology has made significant improvements in these regulators compared to previous devices, such as 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 Linear Technology’s 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.

Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: Unless otherwise indicated, these specifications apply: |VIN – VOUT| = 5V; and IOUT = 5mA. Power dissipation is internally limited. However, these specifications apply for power dissipation up to 30W.
