AN79Lxx/AN79LxxM Series
3-pin negative output voltage
regulator (100 mA type)
I Overview
The AN79Lxx series and the AN79LxxM series are 3-pin, fixed negative output type monolithic 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 capacity of up to 100mA. AN79Lxx series
