AN79M00/AN79M00F Series
3-pin Negative Output Voltage Regulators (500mA Type)
s Overview
The AN79M00 and the AN79M00F series are 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 ; –5V, –5.2V, –6V, –7V, –8V, –9V, –10V, –12V, –15V, –18V, –20V and –24V. They can be used widely in power circuits with current capacitance up to 500mA.
