The SP828/829 devices are 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 50A for the SP828 and 130A for the SP829. Both devices can output 25mA with a voltage drop of 500mV. These devices combine a low quiescent current with high efficiency (>95% over most of its load-current range). The SP828/829 provide a stable operating frequency, low output resistance and low EMI to enhance performance of critical analog circuitry. The SP828/829 devices are available in a space-saving 5-pin SOT23 Package.
