SURFACE MOUNT POSITIVE ADJUSTABLE

1.5 AMP VOLTAGE REGULATOR

Isolated Hermetic Surface Mount Package

1.5 Amp, High Voltage, Positive Adjustable

Voltage Regulator

FEATURES

• Hermetic Isolated Surface Mount Package

• Adjustable Output Voltage

• Eliminates Stocking Fixed Voltages

• Built-In Thermal Overload Protection

• Short Circuit Current Limiting

DESCRIPTION

This three terminal positive regulator is supplied in a hermetically sealed 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 1.5 amp of output current. This unit features output voltages that can be

trimmed using external resistors, from 1.2 volts to 57 volts.

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.
