E-CMOS EC8803XXA6NG2 4- low 300ma linear regulator Datasheet

EC8803
4- Low 300mA Linear Regulator
Description
The EC8803 is a 4-Low (Low-dropout, Low-noise,
Low-quiescent current, Low-cost) linear regulator
that operations in the input voltage range from
+2.2V to +7.0V and delivers 300mA output current.
Features
 Operating Voltages Range:+2.2V to +7.0V
 Output Voltages Range:+1.2V to +5.0V with 100mV
Increment
 Maximum Output Current:300 mA
 Low Dropout: 125mV @ 100mA (VOUT≧2.0 V)
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
with 100mV increment, except EC8803 which
has 2.85V output voltage.
 ±2% Output Voltage Accuracy (special ±1% highly
accurate)
 Output Current Limit Protection (500mA)
 Short Circuit Protection (150mA)
 Thermal Overload Shutdown Protection
The EC8803 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
EC8803 devices are available in SOT-23,
TSOT-23, SOT-89 and TO-92 packages.
 Low ESR Capacitor Compatible
 SOT-23, TSOT-23, SOT-89, TO-92 Packages
 RoHS Compliant and 100% Lead (Pb)-Free and Green
(Halogen Free with Commercial Standard)
Applications
 Battery powered equipments
 Palmtops
 Reference voltage sources
 Portable Cameras and video recorders
 Post Regulator for switching power

Note:
*Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only, and function operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for
extended periods may affect device reliability.
* The power dissipation of UFN-6 would be 500 mW normally with the 0.5X0.5 square inches cooper area connected to
the bottom pad. However, it could be up to 1000mW with larger cooper area.
