Isolated Hermetic Package, JEDEC TO-257AA Outline
Adjustable Output Voltage
Eliminates Stocking Fixed Voltages
Built-In Thermal Overload Protection
Short Circuit Current Limiting
Product Is Available Screened To OM803
Similar To Industry Standard P/N LM117
DESCRIPTION
This three terminal positive regulator is supplied in a hermetically sealed metal
package whose outline is similar to the industry standard TO-220 plastic 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.
