Absolute Maximum Ratings
(Note 4) (@TA = +25°C, unless otherwise specified.)
Symbol Parameter Ratings Unit
ESD HBM Human Body Mode ESD Protection 2 kV ESD CDM Charge Device Model 500 V VIN Input Voltage 6.0 V VEN Input Voltage for EN Pins 6.0 V VOUT Output Voltage -0.3 to VIN + 0.3 V IOUT Each Channel Output Current 300 mA P D (Note 5) Power Dissipation 600 mW TA Operating Ambient Temperature -40 to +85 °C TSTG Storage Temperature -55 to +125 °C Notes: 4. a). Stresses beyond those listed under Absolute Maximum Ratings can cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to absolute-maximum-rated conditions for extended period can affect device reliability. b). Ratings apply to ambient temperature at +25°C. The JEDEC High-K board design used to derive this data was a 2 inch 2 inch multilayer board with 1oz. internal power and ground planes and 2oz. copper traces on the top and bottom of the board. 5. Even though AP7348 would provide each channel 300mA, user still need consider power dissipation can’t over 600mW, or it will enable OTP function and get abnormal output voltage.
Recommended Operating Conditions
(@TA = +25°C, unless otherwise specified.)
Symbol Parameter Min Max Unit
VIN Input Voltage 1.7 5.25 V IOUT Each Channel Output Current 0 300 mA TA Operating Ambient Temperature -40 +85 °C AP7348 3 of 15 October 2019 Document number: DS42124 Rev. 2 - 2
