Note:

1. VOUT means the output voltage when “VOUT + 1.0V” is provided at the VIN pin while maintaining a certain IOUT value.

2. VIN1 is defined as the input value that is gradually decreased until the output value reaches VOUT x 98%.

3. Vdif is defined as “VIN1-VOUT.”

4. IOUT: this is limited by continuous total power dissipation in the package.

5. When VCE is LOW or OPEN, the output is disabled.

Note: CE pin is a CMOS input. Because of this, when the input voltage reaches VIN/2, a rush current will start to flow.
