The AP131 is a 300mA, fixed output voltage, low dropout linear
regulator. The Device included pass element, error amplifier,
band-gap, current limit and thermal shutdown circuitry. The
device is ON when the EN pin is set to logic high level.
The characteristics of low dropout voltage and less quiescent
current make it good for some critical current applications, for
example, some battery powered devices. The typical quiescent
current is approximately 50µA from zero to maximum load. Due
to the internal flexible design, it results in extensively fixed output
voltage versions and makes it convenient to use for applications.
Built-in current-limit and thermal- shutdown functions prevent any
fault condition from IC damage. An external capacitor can be
connected to the BP pin and reduce the output noise.

Note: 4. 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 VOUT inside target value ±2%. This test is skipped at the condition of VIN<3V.
5. Current limit is measured at constant junction temperature by using pulsed testing with a low ON time.
6. Regulation is measured at constant junction temperature by using pulsed testing with a low ON time.
7. Guaranteed by design.
