Overview
August 2002 com LM2787 Low Noise Regulated Switched Capacitor Voltage Inverter in micro SMD LM2787 Low Noise Regulated Switched Capacitor Voltage Inverter in micro SMD General Description The LM2787 CMOS Negative Regulated Switched Capacitor Voltage Inverter delivers a very low noise adjustable output for an input voltage in the range of +2.
7V to +5.
5V.
Four low cost capacitors are used in this circuit to provide up to 10mA of output current.
The regulated output for the LM2787 is adjustable between −1.
5V and −5.
2V.
The LM2787 operates at 260 kHz (typical) switching frequency to reduce output resistance and voltage ripple.
With an operating current of only 400 µA (charge pu...
