LT1033 3A Negative Adjustable Regulator Fea T Descrip T n Guaranteed 1% Initial Voltage Tolerance The LT 1033 negative adjustable regulator will deliver n Guaranteed 0.015%/V Line Regulation up to 3A output current over an output voltage range of n Guaranteed 0.02%/ W Thermal Regulation 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%. p Di T The LT1033 is easy to use and difficult to damage. Internal n 100% Thermal Limit Burn-In 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. a T Maximum reliability is attained with Linear Technologys n Adjustable Power Supplies advanced processing techniques combined with a 100% n System Power Supplies burn-in in the thermal limit mode. This assures that all n Precision Voltage/Current Regulators device protection circuits are working and eliminates field n On-Card Regulators failures experienced with other regulators that receive only standard electrical testing.
