_______________General Desc ription
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
(V
CTRL
), 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).
