Application Note
1. Recommended Application Circuit
The figure above shows the recommended configuration for using a Low-Dropout regulator. Insert a capacitor
at V
OUT
and V
IN
pins for stable input/output operation. (Ceramic capacitors can be used).
2.
Power Dissipation
Power dissipation is measured on the board condition shown below.
[The Board Condition]
Board material: Glass epoxy (FR4)
Board dimension: 40mm x 40mm (both sides of board)，t=1.8mm
Metal pattern ratio: a surface approximately 50%, the reverse side approximately 50%
Through hole: diameter 0.5mm x 28
