Integrated Cellular RF-Section  
Power-Management IC  
General Description  
Features  
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.  
ꢀ Three 100mA Low-Dropout Linear Regulators

ꢀ
ꢀ Preset 1.8V to 3.3V ꢁutput Voltages  
(in 50mV Inꢂrements)  
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.

ꢀ Low 180µA ꢁperating Supplc Current  
ꢀ 2.5V to 5.5V Input Voltage Range  
ꢀ 67dB PSRR  
Each LDO has its own individual enable (ON/OFF) con-  
trol to maximize design flexibility. The reference is pow-  
ered 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 sup-  
plying 100mA with a low 50mV dropout and is opti-  
mized for low noise and high crosstalk-isolation.  
Designed with internal P-channel MOSFET pass transis-  
tors, the MAX8890’s low 180µA operating supply cur-  
rent is independent of load.

*Each preset output voltage of these devices is factory  
trimmed to one of ten voltages. Replace “xyz” with the letters  
corresponding to the desired output voltages (see Standard  
Preset Output Voltage Suffixes table), where the three letter  
suffix corresponds to the following output voltages: “x” =  
with a metal pad on the underside.

Note: There are five standard versions available (see Standard  
Versions table). Sample stock is generally held on standard  
versions only. Standard versions have an order increment  
requirement of 2500 pieces. Nonstandard versions have an  
order increment requirement of 10,000 pieces. Contact the  
factory for availability of nonstandard versions.
