AN8025
3-pin, positive output, low dropout voltage regulator (50 mA type)
Overview
The AN80xx series are 3-pin, low dropout, fixed positive output type monolithic voltage regulators.
Since their power consumption can be minimized, they are suitable for battery-used power supply and reference voltage.
13 types of output voltage are available ; 2 V, 2.5 V, 3 V, 3.5 V, 4 V, 4.5 V, 5 V, 6 V, 7 V, 8 V, 8.5 V, 9 V, and 10 V.

OUT
: AN80xx series have their internal gain in order to improve performance. When the power line on the
output side is long, use a capacitor of 10
μF.
Also, the capacitor on the output side should be attached as close to the IC as possible.
When using at a low temperature, it is recommended to use the capacitors with low internal impedance
(for example, tantalum capacitor) for output capacitors.
