General Descriptions
The AP130 is a 300mA, fixed output voltage, low
dropout linear regulator. The Device includes pass
element, error amplifier, band-gap, current-limit and
thermal shutdown circuitry. The characteristics of
low dropout voltage and less quiescent current
make it good for some critical current application,
for example, some battery powered devices. The
typical quiescent current is approximately 50µA
from zero to maximum load. Due to internal flexible
design, result in extensively fixed output voltage
versions and make it convenient to use for
applications.
Built-in
current-limit
and
thermal-shutdown functions prevent any fault
condition from IC damage.
Applications
- Wireless Communication
- Battery Powered device
- CD-ROM, DVD, and LAN Card
- PC peripheral

Note 1.
Dropout voltage is defined as the input to output differential voltage. Dropout is measured at constant junction temperature by
using pulsed ON time, and the criterion is V
OUT
inside target value ±2%. This test is skipped at the condition of V
IN
<3V.
Note 2.
Current limit is measured at constant junction temperature by using pulsed testing with a low ON time.
Note 3.
Regulation is measured at constant junction temperature by using pulsed testing with a low ON time.
Note 4.
Guaranteed by design.

Function Description
A minimum of 10µF capacitor must be connected from OUT to ground to insure stability. Typically a large
storage capacitor is connected from V
IN
to ground to ensure that the input voltage does not sag below the
minimum dropout voltage during the load transient response. This pin must always be 0.7V higher than V
OUT
in order for the device to regulate properly.
