AN79M00/AN79M00F Series
3-pin Negative Output Voltage Regulators (500mA Type)
■ Overview
The AN79M00 and the AN79M00F series are 3-pin
fixed ne gative 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.
■ Features
• No external components
• Output voltage : –5V, –5.2V, –6V, –7V, –8V, –9V, –10V,
–12V, –15V, –18V, –20V, –24V
• Short-circuit current limiting built-in
• Thermal overload protection built-in
• Output transistor safe area compensation
