Positive Voltage Regulators
00000These voltage regulators are monolithic
integrated circuits designed as fixed-voltage
regulators for a wide variety of applications including
local, on-card regulation. These regulators employ
internal current limiting, thermal shutdown, and
safe-area compensation. With adequate heatsinking
they can deliver output currents in excess of 1.0A.
Although designed primarily as a fixed voltage
regulator, these devices can be used with external
components to obtain adjustable voltages and

00 A common ground is required between the input
and the output voltages. The input voltage must
remain typically 2.0V above the output voltage even
during the low point on the input ripple voltage.
*C in is required if regulator is located in
0 appreciable distance from power supply filter.
**C O is not needed for stability; however, it does
00 improve transient response.
