5 / 23 page  LM3241 www.ti.com SNOSB38B – JANUARY 2009 – REVISED APRIL 2013 SYSTEM CHARACTERISTICS The following spec table entries are guaranteed by design providing the component values in the Typical Application Circuit are used. These parameters are not verified by production testing. Min and Max values apply over the full operating ambient temperature range (-30°C ≤ TA ≤ 85°C) and over the VIN range = 2.7V to 5.5V unless otherwise specified. L = 0.47 µH, DCR = 50 m Ω, CIN = 10 µF, 6.3V, 0603 (1608), COUT = 4.7 µF, 6.3V, 0603 (1608).
