AP1722A Series
Anwell Semiconductor Corp.
4- Low 300mA Linear Regulator
Features
General Description
l
The AP1722A is a 4-Low (Low-dropout, Low-noise,
Operating Voltages Range：+2.2V to +7.0V Low-quiescent current, Low-cost) linear regulator
l Output Voltages Range：+1.2V to +5.0V with that operations in the input voltage range from
+2.2V to +7.0V and delivers 300mA output current.
100mV Increment
l Maximum Output Current：300 mA
l Low Dropout: 125mV @ 100mA
The high-accuracy output voltage is preset at an
internally trimmed voltage 2.5V or 3.3V. Other output
voltages can be mask-optioned from 1.2V to 5.0V
(VOUT≧2.0 V)
with 100mV increment, except AP1722A-LL which
has 2.85V output voltage.
l ±2% Output Voltage Accuracy (special ±1%
highly accurate)
l High Ripple Rejection：65 dB
l Output Current Limit Protection (500mA)
l Short Circuit Protection (150mA)
l Thermal Overload Shutdown Protection
The AP1722A consists of a 1.25V band-gap
reference, an error amplifier, and a P-channel pass
transistor. Other features include short-circuit
protection and thermal shutdown protection. The
AP1722A devices are available in SOT-23, SOT-89
And TO-92 packages.
l Low ESR Capacitor Compatible
l SOT-23, SOT-89 and TO-92 Packages
l RoHS Compliant and 100% Lead (Pb)-Free
Applications
l Battery powered equipments
l Palmtops
l Portable Cameras and video recorders
l Reference voltage sources
l Post Regulator for switching power
