Hermetic Surface Mount Package
Output Voltages: -5V, -12V, -15V
Output Voltages Set Internally To ±1%
Built-In Thermal Overload Protection
Short Circuit Current Limiting
Product Is Available Hi-Rel Screened
DESCRIPTION
These negative regulators are supplied in a hermetically sealed surface mount 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 .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.
