Note: Unless otherwise indicated, VIN = 3.8V, CIN = 10 µF ceramic (X5R), COUT = 1 µF ceramic (X5R), ILOAD = 100 µA,

SELECT12 = NC, SELECT34 = VIN, SHDN1/2/3/4 = VIN, TA = 25°C.

Junction temperature (TJ) is approximated by soaking the device under test at an ambient temperature equal to the

desired Junction temperature. The test time is small enough such that the rise in the Junction temperature over the

Ambient temperature is not significant.
