1. Typical dropout voltages have been measured at currents: Output1: 25 mA, Output2: 35 mA, Output3: 40 mA, Output4: 140 mA, Output5: 40 mA
Maximum value of dropout voltages are measured at maximum specified current.
2. See package power dissipation and thermal protection.
3. Maximum Output Currents are peak values. Total DC current have to be set upon maximum power dissipation specification.
Only Output 3 has been designed to be stable at minimum current of 0 mA.
