The LP38869EVAL/NOPB is an evaluation board for the LP38869 linear voltage regulator. This evaluation board can be used to rapidly evaluate an on-board regulation of the low and high-side outputs. The LP38869EVAL/NOPB board helps to evaluate the features of the linear voltage regulator, such as linear regulation, over-temperature protection, and short-circuit protection for low and high-side outputs.

This evaluation board employs a programmable voltage reference to provide a reference voltage of up to 5 V. The LP38869 linear voltage regulator is capable of providing different output voltages from 0.75 V to 4.25 V. The output voltage of this board can be adjusted using the voltage reference and the on-board adjust pot. The board also includes a power-on reset circuit to detect and reset the output voltage when the voltage reference drops below 0.8 V.

The LP38869EVAL/NOPB has a wide temperature range of -40 °C to +85 °C. It is a low-power device and has an operating current range of 40 mA up to 150 mA. The quiescent current of the LP38869 is low, with a typical value of 3 mA. TheLP38869EVAL/NOPB board also offers a wide output voltage range of up to 4.25 V. Furthermore, the board features low ESR noise filtering capacitors as well as an adjustable pull-down resistor.

In order to evaluate the performance of the LP38869 linear voltage regulator, the first step is to adjust the output voltage of the LP38869EVAL/NOPB board. This can be done by adjusting the voltage reference using the on-board adjust pot. The second step is to measure the output voltage of the board for different input and output voltage combinations. This measurement can be done using an oscilloscope, DVM, or other suitable measuring device.

Once the output voltage has been measured, it can be compared with the specified output voltage for the system. The output voltage can also be adjusted with the voltage reference to ensure it remains within the expected range. In addition, the board has a reset circuit which detect and reset the output voltage when the voltage reference drops below 0.8 V. The reset circuit should be tested to ensure that it is functioning properly.
