_______________Ge n e ra l De s c rip t io n

The MAX850–MAX853 low-noise, inverting, charge-

pump power supplies are ideal for biasing GaAsFETs in

cellular telephone transmitter amplifiers.

____________________________Fe a t u re s

♦ Fixed -4.1V or Adjustable -0.5V to -9V Output at 5mA

♦ 4.5V to 10V Input Voltage Range

♦ 2mVp-p Output Voltage Ripple (MAX850–MAX852)

1mVp-p Output Voltage Ripple (MAX853)

The MAX850–MAX852 offer both preset (-4.1V) and

a d jus ta b le (-0.5V to -9.0V) outp ut volta g e s . 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.

♦ 100kHz Charge-Pump Switching Frequency

(MAX850/MAX851/MAX853)

♦ External Synchronizing Clock Input (MAX852)

An internal linear regulator reduces the output voltage

ripple to 2mVp-p. With a well-filtered control voltage

♦ Logic-Level Shutdown Mode: 1µA Max Over

Temperature (MAX850/MAX852/MAX853)

), the MAX853 achieves typical output ripple of

CTRL

♦ Low Cost, 8-Pin SO Package

less than 1mVp-p. Supply current is 3mA max, and

shutdown current is less than 1µA max over temperature

(5µA max for MAX851).
