Note: 1. Please always keep V_CNTL-V_OUT>1.9V for good regulation.
2. Please supply enough voltage to V_IN for sourcing desired maximum output current. Please refer to the V_IN
Dropout Voltage vs. Output Current in the Typical Characteristics.
3. The V_OUT is regulated to the V_REF with additional voltage offset and load regulation except over-load
conditions.
4. The symbol “+” means the V_OUT sources current to load; the symbol “-“ means the V_OUT sinks current to
GND.
5. The max. I_OUT varies with the T_J and the voltages of V_IN-V_OUT and V_OUT. Please refer to the Typical
Characteristics.
