SE8801EBK

SE8801 Low Quiescent Current LDO General Description Features The SE8801 is a very low dropout three-terminal       regulator and specifically designed for today’s electricity meter applications. There are two distinct requirements for the power supplies for the electricity meters. The first requirement is low power consumption. The second is low noise. Most of the Output voltage of 3.3/4.3/5.0V/5.7 (Typ.) Low quiescent Current Over-current/Over-temperature Protection. Minimum external components. Output voltage tolerances of 4.3V ±1% Output voltage tolerances of 3.3V/5.0V/5.7V power supplies in the market could only satisfy one ±2%  The SE8801 is now the first IC in the market that is  able to satisfy both requirements. The SE8801 uses a  ESD rating is 2KV (Per MIL-STD-883D) very unique design to achieve very low power +125°C requirement, but not both of them at the same time. Input Voltage up to 30V Operating Junction Temperature from −40°C to consumption while providing a very low noise power output for electricity meter applications. Pin Configuration Applications  Electricity meter.  Networking Equipments where low noise and low power consumption is required.
