Three Terminal, Fixed Voltage, 1.5 Amp
Precision Positive Regulators In Hermetic
Surface Mount Package
HERMETIC SURFACE MOUNT FIXED VOLTAGE POSITIVE
REGULATORS APPROVED TO DESC DRAWINGS
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
• Hi-Rel Screening Available
DESCRIPTION
These three terminal positive 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.

3. If not tested, shall be guaranteed to the specified limits.
The • denotes the specifications which apply over the full operating temperature range.
