HERMETIC SURFACE MOUNT FIXED VOLTAGE NEGATIVE

REGULATORS APPROVED TO DESC DRAWINGS

Three Terminal, Fixed Voltage, 1.5 Amp

Precision Negative Regulators In Hermetic

Surface Mount Package

FEATURES

Hermetic Surface Mount Package

Output Voltages: -5V, -12V, -15V

Output Voltages Set Internally To ±1%

Built-In Thermal Overload Protection

Short Circuit Current Limiting

Product Is Available Hi-Rel Screened

DESCRIPTION

These three terminal negative regulators are supplied in a hermetically sealed surface mount package. All protective features are designed into the circuit including thermal shutdown, current limiting and safe-area control. With heat sinking, they can deliver over 1.5 amps of output current. These units feature internally trimmed output voltages to ±1% of nominal voltage. Standard voltages are -5V, -12V, and -15V. These units are ideally suited for Military applications where a hermetic surface mount package is required.

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.

Short Circuit protection is only assured up to V

IN = -35V.

3.

If not tested, shall be guaranteed to the specified limits.

 

The • denotes the specifications which apply over the full operating temperature range.
