• Typical Operating Circuit Using SP828 Negative Voltage Converter, this Circuit Was Used to Obtain the Typical performance Characteristics. The SP828 device is CMOS Charge Pump Voltage Inverters that can be implemented in designs requiring a negative voltage from a +5V supply. The SP828/829 devices are ideal for both battery-powered and board level voltage conversion applications with a typical operating current of 50 uA for the SP828 and 130 uA for the SP829. Both devices can output 25mA with a voltage drop of 500mV
