Maxim MAX8511EXK29+

Позитив6V120 мА

Overview

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).
