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 constant junction 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 specifications which apply over the full operating temperature range.
