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 50
μ
A for the
SP828
and 130
μ
A 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.
