Description
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, results 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.

2. 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.
3. Current limit is measured at constant junction temperature by using pulsed testing with a low ON time.
4. Regulation is measured at constant junction temperature by using pulsed testing with a low ON time.
5. Guaranteed by design.

Functional Descriptions
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.
