Applications Guide E-5
Figure E-5 shows the output voltage and current response of channel #1 with a GSM phone
for output impedance values of 0.00Ω, 0.
05Ω, and 0.10Ω. The voltage drop, 70mV in E-5c and
140mV in E-5e, is approximately equal to the dynamic load current, 1.4A, multiplied by the
output impedance, E-5c (0.05Ω) and E-5e (0.10Ω).
