ISOLATED HERMETIC TO-257AA FIXED

VOLTAGE NEGATIVE REGULATORS

Three Terminal, Fixed Voltage, 1.5 Amp

Precision Negative Regulators In Hermetic

JEDEC TO-257AA Package and D²Pac

FEATURES

• Isolated Hermetic Package, JEDEC TO-257AA Outline

• Output Voltages: -5V, -12V, -15V (Other Voltages Available)

• Output Voltages Set Internally To ±1% or ±2%

• Built-In Thermal Overload Protection

• Short Circuit Current Limiting

• Product Is Available Screened To MIL-STD-883

DESCRIPTION

These three terminal negative regulators are supplied in a hermetically sealed

metal package whose outline is similar to the industry standard TO-220 plastic pack-

age. 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%

or 2% of nominal voltage.

Standard voltages are -5V, -12V, and

-15V. However, other voltages are available up to -24 volts. These units are ideally

suited for Military applications where a hermetically sealed package is required.
