MAX850, MAX851, MAX852, MAX853 Low-Noise, Regulated, Negative Charge Pump Power Supplies For GaAsFET Bias

The MAX850 MAX851 MAX852 MAX853 low-noise, inverting, charge-pump power supplies are ideal for biasing GaAsFETs in cellular telephone transmitter Amplifiers
The MAX850 MAX851 MAX852 offer both preset (-4.1V) and adjustable (-0.5V to -9.0V) output voltages. The MAX853 uses an external positive control voltage to set the negative output voltage. Input voltage range for all four devices is 4.5V to 10V. Output current is 5mA.
An internal linear Regulator reduces the output voltage ripple to 2mVp-p. With a well-filtered control voltage (VCTRL), the MAX853 achieves typical output ripple of less than 1mVp-p. Supply current is 3mA max, and shutdown current is less than 1A max over temperature (5A max for MAX851 .
