DESCRIPTION

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 50µA for the SP828 and 130µA for the SP829.

Both devices can output 25mA with a voltage drop of 500mV. These devices combine a low

quiescentcurrentwithhighefficiency(>95%overmostofitsload-currentrange).TheSP828/829

provideastableoperatingfrequency,lowoutputresistanceandlowEMItoenhanceperformance

of critical analog circuitry. The SP828/829 devices are available in a space-saving 5-pin

SOT23 Package.
