and SOT-89-5 Packages

Applications

• Notebook Computer

• PDA or Portable Equipments

• Noise-Sensitive Instrumentation Systems

The APL5301/2 series are micropower, low noise, low

dropout linear regulators, which operate from 3V to

6V input voltage and deliver up to 300mA. Typical

dropout voltage is only 260mV at 300mA loading. De-

signed for use in battery-powered system, the low 50uA

quiescent current makes it an ideal choice. Design

with an internal P-channel MOSFET pass transistor,

the APL5301/2 maintain a low supply current, inde-

pendent of the load current and dropout voltage.

Other features include reverse current protection, ther-

mal-shutdown protection, current limit protection to

ensure specified output current and controlled short-

circuit current. The APL5301/2 regulators come in a

miniature SOP-8, SOT-23, SOT-23-5, SOT-89 and

SOT-89-5 packages.
