Positive Voltage Regulators
IMAGE SERVES AS A REPRESENTATION ONLY
ABSTRACT
This family of three terminal positive
adjustable voltage regulators are designed to
provide 7.5A, 5A, 3A, and 1.5A with higher
efficiency than conventional voltage
regulators. The devices are designed to
operate to 1 Volt input to output differential
and the dropout voltage is specified as a
function of load current. All devices are pin
compatible with older three terminal
regulators. Supplied in the easy-to-use
hermetic metal TO-257 and TO-258 JEDEC
packages, also supplied in a new surface-
mount D² package. These devices are ideally
suited for Military applications where small
size, hermeticity and high reliability are
required.
