Please see mechanical outlines herein
FEATURES
* * * * * Similar To Industry Standard LM117 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.

STANDARD APPLICATION
Vin Vout OM1320STM R1 240 IAdj Cin* 0.1 F R2 Adjust Co** 1.0 F
* Cin is required if regulator is located an appreciable distance from power supply filter. ** Co is not needed for stability, however it does improve transient response. R Vout = 1.25 V (1 + 2 )+ IAd j R2 R1 Since IAdj is controlled to less than 100 A, the error associated with this term is negligible in most applications.
