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.

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. E-CMOS Corp. (www.ecmos.com.tw) Page 4 of 16 5F15N Rev.
