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.

Notes: 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
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.
6. Test condition for SC59/SC59R: Devices mounted on FR-4 PC board, 1
minimum recommended pad layout.
7. Test condition for SOT23: Devices mounted on FR-4 PC board, 1
8. Test condition for SOT89-3L/SOT89R-3L: No Heat Sink, no air flow.
