809R0

(COTS) COMMERCIAL OFF-THE-SHELF 1.5 AMP POSITIVE

ADJUSTABLE VOLTAGE REGULATOR IN TO-257 PACKAGE

COM117T

FEATURES

• Built In Thermal Overload Protection

• Short Circuit Current Limiting

DESCRIPTION

These three terminal positive regulators are supplied in hermetically sealed packages.

All protective features are designed into the circuit, including thermal shutdown,

current-limiting, and safe-area control. With heat sinking, these devices can deliver up

to 1.5 amps of output current. The unit also features output voltages that can be fixed

from 1.2 volts to 37 volts using external resistors.
