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 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.
I Features
• No external components
• Output voltage: −4V, −5V, −6V, −7V, −8V, −9V,−10V,
−12V, −15V, −18V, −20V, −24V
• Built-in overcurrent limit circuit
• Built-in thermal overload protection circuit
