100-mA 30-V linear voltage regulator

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.
