Evaluation Board for SOT23-5

- Small Size

(i.e., Chip Inductor)

Notes:

(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).
