3 Description

The UA78L series of fixed-voltage linear regulators is

designed for a wide range of applications. The UA78L

series can be used for on-card regulation to eliminate

the noise and distribution problems associated with

single-point regulation. The UA78L can also be

used with power-pass elements to make high-current

voltage regulators. The UA78L series regulators can

deliver up to 100 mA of output current. Additionally,

the UA78L does not need an external capacitor

for stable operation across the load current range.

The internal current-limiting and thermal-shutdown

features of these regulators help protect the device

from overload.

For the legacy chip, the UA78L00C and UA78L00AC

series are characterized for the junction temperature

range of 0°C to +125°C and the UA78L05AI device

is characterized for the operating junction temperature

range of –40°C to +125°C.

For the new chip, the UA78L series is characterized

for the junction temperature range of –40°C to

+125°C.
