ACE78LXX

Positive Voltage Regulator

VER1.2

1 

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 0℃ to +125℃.
