The SE8803 is a regulator with very low dropoutand dual-output. It specifically designed for today'selectricity meter applications.The SE8803 has two voltage inputs and twovoltageoutputs. Output1 hastwodistinctrequirements for the power supplies for the electricitymeters.The firstrequirement is lowpowerconsumption. The second is low noise.Output1uses a very unique design to achieve very low powerconsumption while providing a very low noise poweroutput for electricity meter applications.The second output is capable of delivering150mA output current at a very low dropout voltage of0.82V (Typical). The high precision output at 2%ensures that the accurate power supply requirementismet with enough margins in many toughapplications.Both of Outputs also provides Over CurrentProtection (OCP) and Over Temperature Protection(OTP), these features will ensure a safe operatingenvironment for electricity meter applications.The SE8803 is available in SOP and PSOP8package. 特点
