Approved To DESC Standardized Military Drawing Number 7703401
Built In Thermal Overload Protection
Short Circuit Current Limiting
Available In Six Package Styles
DESCRIPTION
These three terminal positive regulators are supplied in hermetically sealed
packages. 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 LCC-20 device is limited to .5
amps. The unit also features output voltages that can be fixed from 1.2 volts to 37
volts using external resistors.
