(COTS) COMMERCIAL OFF-THE-SHELF FIXED

V O LTAGE NEGATIVE REGULATORS IN TO-257

8 09 R0

FEATURES

• Isolated Hermetic Package, JEDEC TO-257AA Outline

• Output Voltages: -5V, -12V, - 1 5 V

• Output Voltages Set Internally To ± 2%

• Built-In Thermal Overload Protection

• Short Circuit Current Limiting

• Standard Off-The-Shelf

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

package.

shutdown, current limiting and safe-area control. With heat sinking, they can deliver

over 1.5 amps of output current.

voltages to 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.
