GSM Cellular/PCN Handset RF Power  
Management IC  
General Description  
Features  
The MAX1727 is a radio frequency (RF) power-man-  
agement IC intended for Global Satellite Mobile (GSM)  
communication cellular and personal cellular network  
(PCN) handsets using a single lithium-ion (Li+) cell bat-  
tery with inputs from +3.1V to +5.5V. The IC contains  
four low-noise, low-dropout (LDO) linear regulators to  
provide all the supply voltage requirements for the RF  
portion of the handset, and two high-speed, wide-band-  
width op amps for the power amplifier (PA) power con-  
trol loop.  
ꢀ +3.1V to +5.5V Input Range  
ꢀ One 2.90V, 100mA Low IQ LDO  
ꢀ One 2.75V, 50mA Low IQ LDO  
ꢀ One 2.75V, 20mA Low IQ LDO  
ꢀ Low-Noise LDOs  
<90µV  
from 10Hz to 100kHz  
RMS  
>80dB Crosstalk Isolation at 10kHz  
>70dB PSRR at 1kHz  
Each LDO has its own individual on/off control to maxi-  
mize design flexibility. All LDOs are internally trimmed  
to a fixed output voltage and are optimized for low  
noise and high crosstalk isolation. LDO1 (R1OUT) is  
rated for 100µA and is optimized for lowest quiescent  
current. It is intended to power the transmitter, receiver,  
and synthesizer. LDO2 (R2OUT) is rated for 50mA. It is  
intended to power the TCXO, GSM, and PCN high-  
power voltage-controlled oscillators (VCOs). LDO3  
(R3OUT) is rated for 20mA and is optimized to sup-  
press line transients. It is intended to power the UHF  
offset VCO. LDO3 has an auxiliary 2.5Ω switched out-  
put to allow the VCO to be powered up with precise  
timing. LDO4 (R3BYP) is rated for 20mA. It is intended  
to power this IC’s reference and LDO3 for superior line  
rejection. LDO4 and the reference will be powered on if  
any of the R1EN, R2EN, and R3EN enable inputs are  
logic high.

The op amps have wide bandwidth, high DC accuracy,  
high slew rate, and Rail-to-Rail® inputs and outputs.  
The op amps can sink and source 3mA, and include  
two 2.5Ω switched outputs. The op amps and switched  
outputs may be used independently or may be config-  
ured to provide optimized power for a PA control loop.
