Notes :

1. Please refer to the VCNTL-to-VIN Dropout Voltage in the “Typical Characteristics” section for the minimum supply voltage on

VCNTL.

2. Please supply enough voltage to VIN for sourcing desired maximum output current. Please refer to the VIN. Dropout Voltage vs

Output Current in the Typical Characteristics.

3. The VOUT is regulated to the VREF with additional voltage offset and load regulation except over-load conditions.

4. The symbol “+” means the VOUT sources current to load; the symbol “-“ means the VOUT sinks current to to GND.

5. The max. IOUT varies with the TJ and the voltages of VIN-VOUT and VOUT. Please refer to the Typical Characteristics.
