LM2787
Low Noise Regulated Switched Capacitor Voltage
Inverter in micro SMD
General DescriptionThe LM2787 CMOS Negative Regulated Switched Capacitor
Voltage Inverter deliversa very low noise adjustable output
foran input voltagein the rangeof +2.7Vto +5.5V. Four low
cost capacitorsare usedin this circuitto provideupto 10mA output current. The regulated outputfor the LM2787is
adjustable between −1.5V and −5.2V. The LM2787 operates 260 kHz (typical) switching frequencyto reduce output
resistance and voltage ripple. Withan operating currentof
only 400 µA (charge pump power efficiency greater than
90% with most loads) and 0.05µA typical shutdown current,
the LM2787 provides ideal performancefor cellular phone
power amplifier bias and other low current, low noise nega-
tive voltage needs. The device comesin small 8-Bump micro
SMD and thin micro SMD packages.
