The MAX881REUB+ is a low-noise, inverting power supply designed for biasing GaAsFET power amplifiers in portable wireless applications. This device integrates a charge-pump inverter followed by a negative linear regulator.
It operates with an input voltage range of 2.5V to 5.5V and can deliver up to 4mA. The output voltage is preset at -2.0V or can be set to any voltage from -0.5V to (-VIN + 0.6V) using two resistors. The internal linear regulator filters the output to achieve a low 1mVp-p ripple and noise.
Key features include a power-OK (POK) output that signals when the negative voltage is within 7.5% of its set point, protecting the GaAsFET by preventing power application until proper biasing is achieved. It also offers a logic-controlled shutdown feature with 0.05µA current consumption and a guaranteed startup time of 1ms. The device is available in a compact 10-pin µMAX package, suitable for space-constrained designs.
Applications for the MAX881REUB+ include cell phones, wireless modems, PCS phones, two-way pagers, PHS phones, mobile radios, wireless handsets, and wireless computers.
