AIC1841, AIC1840, REGULATED GaAsFET BIAS
The AIC1840/1841 is a switched-capacitor voltage inverter that generates a regulated fixed -2.0V or externally adjustable output.
An internal linear post-regulator reduces the output voltage ripple to less than 2mV, making the AIC1840/1841 excellent for use as bias voltage generator for transmitter
AIC1841 Features
* " Low Output Noise: 2mV Ripple. " Work with Small Capacitors (as Low as 0.22µF). " Fixed -2V or Adjustable Output. " 2.5V to 6.5V Input Voltage Range. " Switching Frequency: 104KHz in Normal Operation. " 1µA Maximum in Shutdown Mode. ! APPLICATIONS " Cellular Phones. " GaAsFET Power Amplifier Module
