  • Fully Assembled and Tested

Product Details

The MAX8517 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB demonstrating the MAX8517 low-dropout (LDO) regulator. The EV kit comes assembled with a MAX8517EUB+ circuit that steps down a 1.425V to 3.6V input-voltage range to a 1.2V output capable of sourcing up to 1A of continuous output current, with a maximum dropout voltage of only 200mV. The MAX8517 features a POK output that goes high impedance once the output is within ±10% of its regulation value. Other features of the EV kit include a logic-controlled shutdown mode (EN) and adjustable output voltage through feedback resistors R1 and R2.

The EV kit can also be used to evaluate the MAX8518, which features a POR output that goes high impedance 150ms (typ) after the output has risen above 90% of its final value. Both the POK and POR features require an external pullup resistor to IN. See the Detailed Description of Hardware section in the full data sheet for more details. To evaluate the MAX8516, remove R4 and install a MAX8516 IC.

Although the EV kit is optimized for 1A output current, the part is capable of supporting up to 1.6A output current (limited by power dissipation and dropout).
