300mA LDO Linear Regulator
Features
General Description
l
The AP8853 is a low-dropout linear regulator that
Operating Voltages Range:+2.5V to +9.0V operations in the input voltage range from +2.5V to
l Output Voltages Range:+1.5V to +5.0V with + 9. 0V and deliv ers 300mA out put current .
The high-accuracy output voltage is preset at an
100mV Increment
internally trimmed voltage 2.5V or 3.3V. Other output
l Maximum Output Current:300 mA
l Low Dropout: 120mV @ 100mA
voltages can be mask-optioned from 1.5V to 5.0V
with 100mV increment.
(VOUT≧2.0 V)
l ±2% Output Voltage Accuracy
l High Ripple Rejection:70 dB
l Output Current Limit Protection (600mA)
The AP8853 consists of a 1.25V bandgap reference,
an error amplifier, and a P-channel pass transistor.
Other features include short-circuit protection and
thermal shutdown protection. The AP8853 devices
are available in SOT-23 and SOT-89 packages.
l Short Circuit Protection (300mA)
l Thermal Overload Shutdown Protection
l Low ESR Capacitor Compatible
l SOT-23, SOT-89 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
