AN79Lxx/AN79LxxM Series
3-pin negative output voltage regulator (100 mA type)
■ Overview
AN79Lxx series
Unit: mm
4.0 0.ꢀ
5.0 0.ꢀ
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.

■ Usage Notes
1. Cautions for a basic circuit
CI: When a wiring from a smoothing circuit to a three-pin regulator
is long, it is likely to oscillate at output. A capacitor of 0.1µF to
0.47µF should be connected near an input pin.
Di
CO: Deadly needed to prevent from oscillation (0.33µF to 1.0µF). It
is recommended to use a capacitor of a small internal imped-
ance (ex. tantalum capacitor) when using it under a low tem-
perature.

CO
2
CI
When any sudden change of load current is likely to occur, con-
nect an electrolytic capacitor of 10µF to 100µF to improve a
transitional response of output voltage.
Di: Normally unnecessary. But add it in the case that there is a
residual voltage at the output capacitor Co even after switching
off the supply power because a current is likely to flow into an
output pin of the IC and damage the IC.
Figure 1
2. Other caution items
1) Short-circuit between the input pin and GND pin
If the input pin is short-circuitted to GND or is cut
off when a large capacitance capacitor has been con-
nected to the IC's load, a voltage of a capacitor con-
nected to an output pin is applied between input/out-
put of the IC and this likely results in damage of the
IC. It is necessary, therefore, to connect a diode, as
shown in figure 2, to counter the reverse bias between
input/output pins.

2) Floating of GND pin
If a GND pin is made floating in an operating mode, an unstabilized input voltage is outputted. In this case, a
thermal protection circuit inside the IC does not normally operate. In this state, if the load is short-circuited or
overloaded, it is likely to damage the IC.

Request for your special attention and precautions in using the technical information
and semiconductors described in this material
(1) An export permit needs to be obtained from the competent authorities of the Japanese Government if any of
the products or technical information described in this material and controlled under the "Foreign Exchange
and Foreign Trade Law" is to be exported or taken out of Japan.
(2) The technical information described in this material is limited to showing representative characteristics and
applied circuits examples of the products. It neither warrants non-infringement of intellectual property right
or any other rights owned by our company or a third party, nor grants any license.
(3) We are not liable for the infringement of rights owned by a third party arising out of the use of the technical
information as described in this material.
(4) The products described in this material are intended to be used for standard applications or general elec-
tronic equipment (such as office equipment, communications equipment, measuring instruments and house-
hold appliances).
Consult our sales staff in advance for information on the following applications:
• Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment, combus-
tion equipment, life support systems and safety devices) in which exceptional quality and reliability are
required, or if the failure or malfunction of the products may directly jeopardize life or harm the human
body.
• Any applications other than the standard applications intended.
(5) The products and product specifications described in this material are subject to change without notice for
modification and/or improvement. At the final stage of your design, purchasing, or use of the products,
therefore, ask for the most up-to-date Product Standards in advance to make sure that the latest specifica-
tions satisfy your requirements.
(6) When designing your equipment, comply with the guaranteed values, in particular those of maximum rat-
ing, the range of operating power supply voltage, and heat radiation characteristics. Otherwise, we will not
be liable for any defect which may arise later in your equipment.
Even when the products are used within the guaranteed values, take into the consideration of incidence of
break down and failure mode, possible to occur to semiconductor products. Measures on the systems such
as redundant design, arresting the spread of fire or preventing glitch are recommended in order to prevent
physical injury, fire, social damages, for example, by using the products.
(7) When using products for which damp-proof packing is required, observe the conditions (including shelf life
and amount of time let standing of unsealed items) agreed upon when specification sheets are individually
exchanged.
