Description
3-pin Positive Output Voltage Regulator 300ma Type
Manufacturer
Panasonic Corporation of North America
Datasheet
AN78N00 Series
3-pin Positive Output Voltage Regulator (300mA Type)
age regulators. Stabilized fixed output voltage is obtained
from unstable DC input voltage without using any exter-
nal components. 12 types of fixed output voltage are avail-
able ; 4V, 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, 18V, 20V
and 24V. They can be used widely in power circuits with
current capacitance up to 300mA.
• No external components
• Output voltage : 4V, 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V,
• Short-circuit current limiting built-in
• Thermal overload protection built-in
• Output transistor safe area compensation
The AN78N00 series is 3-pin fixed positive output volt-
