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.

Notes:
1. Load and Line Regulation are specified at a constantjunction temperature. Pulse testing with low duty cycle is used.
Changes in output voltage due to heating effects must be taken into account separately.
2. If not tested, shall be guaranteed to the specified limits.
3. The . denotes the specitications which apply over the full operating temperature range.
