Voltage Regulators
AN79Lxx/AN79LxxM Series
3-pin negative output voltage regulator (100 mA type)
■
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 un-
stable DC input voltage without using any external compo-
nents. 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.
