ISOLATED HERMETIC TO-257AA
ADJUSTABLE VOLTAGE REGULATOR
OM7602ST
Three Terminal, Adjustable Voltage, 1.5 Amp
Precision Positive Regulator In Hermetic
JEDEC TO-257AA Package
FEATURES
• 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.
