Hi,

Could you tell me about LMZ31520 load regulation spec?
The data sheet has the following description.

Please tell me about this measurement condition.
My customers evaluated using EVM.

However,
Load regulation=0.66％　in 0A->20A Vout=0.9V Vin=8V condition.
Could you give me your advice.

Best Regards,

The operating conditions for this test are:

TA = -40°C to 85°C, VIN = 12 V, VOUT = 1.8 V, IOUT = 20A

CIN = 2x 22 μF ceramic & 330 μF bulk, COUT = 4x 100 μF ceramic

For your conditions, I would expect a load regulation of about 0.6% (typ)
