Marking Information
FLx
(1) Measured in free convection, mounted on 10mm x 10mm, 2 layer
FR4 PCB shown in figure 7 ( for MLPD-UT6 package) and figure 8 (
for SOT23-5 package) with copper of 1oz for each layer.
(2) Available in tape and reel only. A reel contains 3,000 devices.
(3) Available in lead-free package only. Device is WEEE and RoHS
compliant.
(4) “x” is the code of the output voltage. See Table 1 for the code. For
example, the device number for VOUT= 1.20V is SC189CULTRT.
(5) “x” is the code of the output voltage. See Table 1 for the code.
For example, the EVB for MLPD-UT6 package with VOUT= 1.20V is
SC189CEVB (Standard Size) or SC189CEVB-1 (Small Size).
