Equivalent Circuit Block Diagram
Test Circuit
Notes: 1. To ensure operational stability, C
IN
, C
OUT
, and Cn should be placed as close to the IC as possible.
2. Because the output capacitor C
OUT
is set at over 100 μF to prevent oscillation at low temperatures, a capacitor that
exhibits little change in capacity with temperature variations should be used (such as a tantalum capacitor).
3. Adding capacitor Cn enables external noise suppression and ripple rejection to be improved. However, attention should
be given to system stability (phase margin).
4. When the strobe (STB) pin is open, output is turned on by internal bias. When the strobe function is not used, the STB
pin should be connected to GND to complete strobe operation.
5. When V
IN
is minus (–) and GND is plus (+) (reversed connection), excessive current flow will occur.
