Isolated Hermetic Surface Mount Package 1.0 Amp, Negative Adjustable Voltage Regulator

Isolated Hermetic Surface Mount Package Adjustable Output Voltage Eliminates Stocking Fixed Voltages Built-In Thermal Overload Protection Short Circuit Current Limiting Product Is Available Hi-Rel Screened Electrically Similar To Industry Standard Type LM137


This three terminal negative regulator is supplied in a hermetically sealed metal surface mount package. All protective features are designed into the circuit, including thermal shutdown, current limiting and safe-area control. With heat sinking, they can deliver over 1.0 amp of output current. This unit features output voltages that can be trimmed using external resistors, from -1.2 volts to -37 volts.
