AN79L00 Datasheet, PDF (1/9 Pages) Panasonic Semiconductor – 3-pin Negative Output Voltage Regulator 100mA Type

AN79L00/AN79L00M Series
3-pin Negative Output Voltage Regulator (100mA Type)
s Overview
The AN79L00 series is 3-pin fixed negative output volt-
age regulator.
Stabilized fixed output voltage is obtained from unstable
DC input voltage without using any external components.
12 types of output voltage are available; –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 100mA.
s Features
• No external components
• Output voltage : –4V, –5V, –6V, –7V, –8V, –9V, –10V,
–12V, –15V, –18V, –20V, –24V
• Short-circuit current limiting built-in
• Thermal overload protection built-in
