Note: 1. Please always keep VCCA -VOUT>1.9V for good regulation.
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 â+â means the VOUT sources current to load; the symbol â-â means the VOUT sinks current to
GND.
5. The max. IOUT varies with the TJ and the voltages of VIN-VOUT and VOUT. Please refer to the Typical
Characteristics.
