General Description
The MAX850–MAX853 low-noise, inverting, charge pump power supplies are ideal
for biasing GaAsFETs in cellular telephone transmitter amplifiers.
The MAX850–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 1µA max over temperature (5µA max for MAX851).
