AN79N00 Series
3-pin Negative Output Voltage Regulator (300mA Type)
s Overview
The AN79N00 series is 3-pin fixed negative output voltage regulators. 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 300mA.
