| Description: 3-Terminal Positive Voltage Regulators
The AX78XX series of three-terminal positive
regulators employ internal current-limiting and
thermal-shutdown, making them essentially indestructible.
They can deliver up to 1A output current.
These voltage regulators are monolithic integrated
circuits designed as fixed-voltage regulators
for a wide variety of applications including local,
on-card regulation. Although designed primarily
as a fixed voltage regulator, these devices can
be used with external components to obtain adjustable
voltages and currents.
Features:
กค Maximum output current of 1A
กค Output voltages of 5V, 6V, 8V, 9V, 12V
กค Internal short-circuit current limiting and
thermal overload protection
กค Good temperature coefficient
Package: TO-220AB, TO-252, TO-251, SOT-82
