REGULATOR APPROVED TO DESC DRAWING 7703402

Three Terminal, Precision Adjustable Positive Voltage Regulator In Hermetic

Style Packages (LM117HV)

Please see mechanical outlines herein

FEATURES

Similar To Industry Standard LM117HV

Approved To DESC Standardized Military Drawing Number 7703402

Built In Thermal Overload Protection

Short Circuit Current Limiting

Available In Six Package Styles

4 11 R2

Supersedes 1 07 R1

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 57 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.
