Voltage Regulators
AN77L00/AN77L00M Series
3-pin Low Power Loss Voltage Regulato r(100mA Type)
■ Overview
AN77L00 Series
The AN77L00/AN77L00M series is a stabilized constant
voltage power supply with a low input/output voltage(0.3V
max.). It is suitable for the low-voltage equipment using
batteries, and consumer/industrial equipment with great
fluctuation of the supply voltage.
A wide range of output voltage is available from 3V
through 10V.

• For the AN77L00/M series, the gain inside the IC is set high to improve the performance. For the reason, use
the capacitor of 10µF or more when the power line in the output side should be long.
In addition, install the capacitor in the output side as near as possible to the IC.

1. Input Short-Circuit Protection Circuit
For the conventional Matsushita 3-pin regulators (such as
of the AN8000 series), when DC input pin3 is shortcircuited with GND w in the normal operation condition,
the potential of output pinq becomes higher than that of
DC input pin and the electric charges which is charged in
output capacitor CO flows in the input side, resulting in the
breakage of elements.
In the above case, the common silicon diode is connected
as shown in the right figure (the dotted line). However, for
the AN77L00/M series, since the protection circuit, which
protects the elements from the discharging current, is
incorporated in the internal circuit, the protection diode is
not required.
2. Capacitor for External Compensation
In order to secure the safety, the capacitor of 10 µF is
required in the output side and it should be added as near
as possible to output pin1 and GND 2. When it is used
under low temperature, oscillation may occur due to the
decrease of the aluminum electrolytic capacitor and
increase of ESR.
For the AN77L00/M, it is recommended that the tantalum
capacitor or aluminum electrolytic capacitor whose serialconnected resistance equivalent with that of output
capacitor CO has temperature characteristics within the
recommended range specified in the right.
