Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended.
P_D(max) = (T_J(max) – T_A) ÷ θ_JA, where θ_JA depends upon the printed curcuit board layout. See “Applications Information.”
Output voltage temperature coefficient is defined as the ∆V_{OUT(worst case)} ÷ (T_J(max) – T_J(min)) where T_J(max) is +125°C and T_J(min) is 0°C.
V_DO = V_IN – V_OUT when V_OUT decreases to 99% of its nominal output voltage with V_IN = V_OUT + 1V.
I_GND is the quiescent current. I_IN = I_GND + I_OUT.
V_EN ≤ 0.8V and V_IN ≤ 8V, V_OUT = 0.
