AN7800R/AN78M00R Series
Positive Output Voltage Regulators with
Reset pin (1A/500mA Type)
s Overview
The AN7800R and the AN78M00R series are the fixed
positive output voltage regulators with reset pin. Stabi-
lized fixed output voltage is obtained from unstable DC
input voltage without using any external components.
Three types of output voltage, 5V, 9V and 12V, are avail-
able for the AN7800R series, and four types, 5V, 8V, 9V
and 12V, are available for the AN78M00R series. They
can be used in power circuits with current capacitance
1A/500mA. ON/OFF of output voltage can be controlled
by the reset pin.
s Features
• No external components
• Maximum output current :1A (AN7800R)
500mA (AN78M00R)
• Output voltage :5V, 9V, 12V (AN7800R)
:8V (AN78M08R)
• Short-circuit current limiting built-in
• Thermal overload protection built-in
• Output transistor safe area compensation
• ON/OFF of output voltage can be controlled by reset
pin.
