Positive Voltage Regulator
Description
The ACE78LXX series of positive regulators are available in the SOT-89-3 package and with 5V, 6V, 8V,
9V, 10V, 12V, 15V, 18V and 24V fixed output voltages, marking it useful in a wide range of applications.
These regulators can provide local on-card regulation, eliminating the distribution problems associated
with single point regulation. Each type employs internal current limiting, thermal shut-down and safe
operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they
can deliver over 100mA output current. Although designed primarily as fixed voltage regulators, these
devices can be used with external components to obtain adjustable voltages and currents. ACE78LXX is
characterized for operation from 0to +125.

Note 1: The Maximum steady state usable output current is dependent on input voltage, heat sinking, lead length of the
package and copper of PCB. The data above represent pulse test conditions with junction temperatures specified at
the initiation of test.
Note 2: Power dissipation<0.5W.
