Similar To Industry Standard LT117AHV
Adjustable Output Voltage
Built In Thermal Overload Protection
Short Circuit Current Limiting
Available In Isolated and Non-Isolated Package
Maximum Output Voltage Tolerance Is Guaranteed To 鹵1%
Available Hi-Rel Screened
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, these devices can deliver up to 1.5
amps of output current. The unit also features output voltages that can be fixed from
1.2 volts to 57 volts using external resistors.
