1 Evaluates: MAX890A/B/C/D General Description The MAX890 evaluation kit (EV kit) evaluates the MAX890A/B/C/D IC family of low noise linear regulators. The MAX890 EV kit features two independent circuits to evaluate two different IC packages of the MAX890A/B/C/D family. Both circuits on the EV kit operate over an input range of.7v to 5.5V, and provide any output voltage range of 0.6V to 5.V. The TDFN circuit evaluates the MAX890A/B, while the wafer-level package (WLP) circuit evaluates the MAX890C/D. Each circuit output on the EV kit delivers up to 500mA of current. The EV kit comes with the MAX890A-ATA+ and the MAX890C-ANT+ installed.

Detailed Description of Hardware The MAX890 EV kit evaluates the MAX890A/B/C/D IC family. The MAX890A/B/C/D are low noise linear regulators that deliver 500mA of output current with only µv RMS of output noise from 0Hz to 00kHz. These regulators require only 00mV of input-to-output headroom at full load. The MAX890 EV kit features two independent circuits to evaluate two different IC packages of the MAX890A/ B/C/D family. Both circuits on the EV kit operate over an input range of.7v to 5.5V. The TDFN circuit evaluates the MAX890A/B, while the WLP circuit evaluates the MAX890C/D. Each circuit output on the EV kit delivers up to 500mA of current. The MAX890 (TDFN) circuit on the EV Kit comes with the MAX890A-ATA+ installed and the output is jumper configurable between.v and 5.0V (Table ), and can deliver 500mA of current. The MAX890 (WLP) circuit on the EV kit comes with the MAX890C-ANT+ installed and the output is resistor configured to.v, and can deliver 500mA of current. The output voltage on the MAX890C can be reconfigured to other voltages from 0.6V to 5.V by replacing feedback resistors R and R. Refer to the MAX890 IC data sheet for feedback resistor calculation. EN for the MAX890C/D (WLP) Circuit The MAX890C/D (WLP) circuit on the EV kit provide a jumper JU to enable or disable the MAX890C (or the MAX890D after IC replacement). Refer to Table for jumper setting of jumper JU. EN for the MAX890A/B (TDFN) Circuit The MAX890A/B (TDFN) circuit on the EV kit provide a jumper JU0 to enable or disable the MAX890A (or the MAX890B after IC replacement). Refer to Table for jumper setting of jumper JU0. Table. EN on MAX890C/D (JU) JU *Default Position -* Enabled. EN = - Disabled. EN = Table. EN on MAX890A/B (JU0) JU *Default Position -* Enabled.

3 Evaluates: MAX890A/B/C/D Output Selection (SELA and SELB) for the MAX890A/B (TDFN) Circuit The MAX890A/B (TDFN) circuit on the EV kit provide a set of jumpers SELA and SELB to configure the output voltage of the MAX890A. Refer to Table for jumper setting of jumpers SELA and SELB. Evaluating the MAX890B The MAX890A/B (TDFN) circuit can evaluate the MAX890B after IC (U0) replacement. When evaluating the MAX890B, modify the EV Kit with the steps listed below: ) Replace U0 with the MAX890B-ATA+. ) Install feedback resistors R0 and R0 to obtain the desired output voltage between 0.6V and 5.V (Refer to the MAX890 IC data for feedback resistor calculations). ) Install a shunt on jumper SELA pins and (GS = ). ) Remove shunt from jumper SELB. POK is accessible on the POK test point. 5) Install a 00kΩ resistor on R0. POK open-drain is pulled up via resistor R0 (When the regulator output reaches its regulation, POK goes low). Evaluating the MAX890D The MAX890C/D (WLP) circuit can evaluate the MAX890D after IC (U) replacement. The MAX890D can be factory trimmed to any voltage between 0.7V and 5.V in 50mV steps. Contact the factory to order the MAX890D with the desired factory-preset output voltages. Table.
