Product Details

The ADPL44002 evaluation boards evaluate the ADPL44002, a 40V, 200mA, low noise, CMOS, low dropout (LDO) linear regulator.

See the Ordering Information section for the two types of evaluation boards available to evaluate the ADPL44002. There is an evaluation board that features a 6-lead, 2mm x 2mm LFCSP package, and there is also an evaluation board that features a 5-lead TSOT package.

The evaluation boards provide a 3.3V output over an input range of 3.8V to 40V. The maximum output current is 200mA, but output current is also limited by the thermal dissipation of the ADPL44002. The evaluation boards use the adjustable version of ADPL44002. A resistor divider programs the output of the adjustable ADPL44002 to 3.3V. Noise performance for the adjustable ADPL44002 can be made comparable to a fixed output ADPL44002 by installing optional RC network components into placeholders that the evaluation board printed circuit board (PCB) designs provide. The evaluation boards can easily be configured with a jumper for fixed output versions of the ADPL44002 that normally have their SENSE/ADJ pin connected directly to the output.

In addition to connectors for the input voltage, output voltage, EN control signal and ground, the evaluation boards provide test points for the input, output, and SS pin voltages. A jumper normally connects the EN pin to the VIN input, but the jumper can be repositioned so EN can be driven externally at its connector instead.

For more details, refer to the ADPL44002 data sheet, which must be consulted in addition to this user guide when using the ADPL44002 evaluation boards.
