MAX8890 Integrated Cellular RF-Section Power-Management IC

The MAX8890 is a power-management IC intended for cellular handsets using a single lithium-ion (Li+) cell battery with input voltages from +2.5V to +5.5V. The IC contains three identical, low-noise, low-dropout (LDO) linear Regulators to provide all of the supply voltage requirements for the RF portion of the handset.
The first LDO is intended to power the transmitter, receiver, and synthesizer. The second LDO is intended to power the TCXO and high-power Voltage-Controlled Oscillators (VCOs). The third LDO is intended to power the UHF offset VCO
Each LDO has its own individual enable (ON/OFF-bar) control to maximize design flexibility. The reference is powered on if any of the enable inputs (EN1, EN2, EN3) are Logic high. The high-accuracy output voltage of each LDO is preset at an internally trimmed voltage (1.8V to 3.3V in 50mV increments). Each LDO is capable of supplying 100mA with a low 50mV dropout and is optimized for low noise and high crosstalk-isolation. Designed with internal P-Channel MOSFET pass Transistors the MAX8890 's low 180A operating supply current is independent of load.
Other features include short-circuit and thermal overload protection. The MAX8890 is available in a compact, high-power, 12-pin 4mm x 4mm QFN package with a metal pad on the underside.
