1.5 AMP NEGATIVE ADJUSTABLE VOLTAGE REGULATOR APPROVED TO DESC DRAWING 7703404

Three Terminal, Precision Adjustable Negative Voltage Regulator In Hermetic

Style Packages (LM137HV)

Please see mechanical outlines herein

FEATURES

•Similar To Industry Standard LM137HV

•Approved To DESC Standardized Military Drawing Number 7703404

•Built In Thermal Overload Protection

•Short Circuit Current Limiting

•Available In Six Package Styles

DESCRIPTION

These three terminal negative 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 -47 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.
