Description

The H (Metal Can), J (Ceramic), and K (Metal Can) Packages From Analog Devices Are Now ObsoleteThe LT137A/LT337A negative adjustable regulators will deliver up to 1.5Amps output current over an output voltage range of - 1.2V to -37V. We have 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%.Every effort has been made to make these devices easy to use and difficult to damage. Internal current and power limiting coupled with 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 our 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.ApplicationsThe H (Metal Can), J (Ceramic), and K (Metal Can) Packages From Analog Devices Are Now ObsoleteAdjustable Power SuppliesSystem Power SuppliesPrecision Voltage/Current RegulatorsOn-Card Regulators
