EV20056-J-00A 3.7-5.5V Ultra-Small 250mA Linear Regulator EV Board Evaluation Board QFN8

The MPS EV20056-J-00A is an evaluation board built around the MP20056-33 for bench characterisation of the device in its intended topology. It operates from a 3.7 V to 5.5 V input and is rated for 250 mA. The board carries the device in its QFN8 package.

The EV20056-J-00A evaluation board demonstrates the performance of MP20056-33, a low noise, low dropout and high PSRR linear regulator.

Design Notes

The board ships in a default configuration; check the jumper and resistor options against the user guide before applying power.
Respect the input terminal rating — most faults on evaluation boards come from an supply above the marked limit.
Test points on the switching node and output are for a short-ground probe, not for a long oscilloscope lead.
Where a GUI is supported, connect the dongle before power-up so the device enumerates on the I²C bus.
