Surface Mount Package

4 11 R0

SURFACE MOUNT POSITIVE FIXED

VOLTAGE REGULATOR

FEATURES

• Hermetic Surface Mount Package

• Output Voltages: +5V, +12V, +15V

• Output Voltages Set Internally To ±2%

• Built-In Thermal Overload Protection

• Short Circuit Current Limiting

• Product Is Available Hi-Rel Screened

DESCRIPTION

This three terminal positive regulator is 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

1.0 amp of output current. This unit features internally trimmed voltages to ±2% 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.
