Application Note
1. Recommended Application Circuit
The figure above shows the recommended configuration for using a Low-Dropout regulator. Insert a capacitor at
VOUT and VIN pins for stable input/output operation. (Ceramic capacitors can be used).
2. Power Dissipation
Both unit and board-mounted power dissipation ratings for TCR2EF series and TCR2EE series are available in
the Absolute Maximum Ratings table.
Power dissipation is measured on the board shown below.
