Features and Benefits

  • 1.425V to 3.6V Input-Voltage Range
  • 1.2V Output Voltage
  • Up to 3A Output Current (Limited by Power Dissipation and Dropout)
  • Low-Dropout Voltage (200mV max at 2A)
  • Power-OK (POK) Output (MAX8527 Only)
  • Power-On Reset (POR) Output (MAX8528 Only)
  • Fully Assembled and Tested

Product Details

The MAX8526 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB demonstrating the MAX8526 low dropout (LDO) regulator. The EV kit comes assembled with a MAX8526EUD+ circuit that steps down a 1.425V to 3.6V input voltage range to a 1.2V output capable of sourcing up to 2A of continuous output current with a maximum dropout voltage of only 200mV. 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 MAX8527, which features a POK output that goes high impedance once the output is within ±10% of its regulation value. The EV kit can also be used to evaluate the MAX8528, 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.

Although the EV kit is optimized for 2A output current, the part is capable of supporting up to 3A output current (limited by power dissipation and dropout).
