Thermal Resistance Junction to Case X1-DFN1612-8 (Type B) — 26 — (JC) Notes: 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. 6. Potential multiple grades based on following output voltage accuracy. 7. Quiescent current is defined here is the difference in current between the input and the output. 8. Short circuit current is measured with VOUT pulled to GND. 9. This specification is guaranteed by design. 10. To make sure lowest environment noise minimizes the influence on noise measurement. 11. Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its nominal value.
