5 / 28 page  LM3205 www.ti.com SNVS388E – JULY 2005 – REVISED APRIL 2013 SYSTEM CHARACTERISTICS The following spec table entries are specified by design providing the component values in the typical application circuit are used. These parameters are not specified by production testing. Min and Max limits apply over the full operating ambient temperature range ( −30°C ≤ TA ≤ 85°C) and over the VIN range = 2.7V to 5.5V, TA = 25°C, PVIN = VDD = EN = 3.6V, L = 3.3µH, DCR of L ≤ 100mΩ, CIN = 10µF, 0603, 6.3V (4.7µF||4.7µF, 0603, 6.3V can be used), COUT = 4.7µF, 0603, 6.3V for LM3205TL/LM3205SD unless otherwise noted.
