SURFACE MOUNT NEGATIVE ADJUSTABLE

3.0 AMP VOLTAGE REGULATOR

Isolated Hermetic Surface Mount Package

3.0 Amp, Negative Adjustable Voltage

Regulator

FEATURES

• Isolated Hermetic Surface Mount Package

• Reference Voltage Set Internally To ±2% (±1% Available)

• Built-In Thermal Overload Protection

• Short Circuit Current Limiting

• Small Metal Package

• Product Is Available Hi-Rel Screened

DESCRIPTION

These three terminal negative regulators are supplied in a hermetic metal 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 3.0 amps of output current. These units feature 2% initial voltage tolerance, with

1.0% load regulation and .015% line regulation.
