ZXTR20XXEV1 USER GUIDE Description The board is intended for the evaluation of ZXTR20XX series high voltage 100V linear regulators with fixed 5V, 8V and 12V output voltages in SOT89, POWERDI5 and TO252. Refer to Table 1 for a detailed description. The board can provide regulated 5V output from an input voltage within the range of 8V to 100V. Regulated 8V and 12V outputs can be provided from input voltage ranges of 12V to 100V and 15V to 100V, respectively. All the outputs can provide up to 50mA The evaluation board is ideal for generating output current. 5V, 8V and 12V from a nominal 24V or 48V rails connected to the common input on the Load can be applied to all the 9 outputs board. It can supply well-regulated voltage either individually or simultaneously as long rails, as well as, withstand and maintain as the maximum temperature rating is not regulation during very high and fast voltage exceeded. Refer to the datasheets for further transients. details on max operating conditions and regulation tolerances.

Required loads can be connected to the test points. Typical performance details are provided in the sections below. ZXTR20XXEV1 Schematic Figure 2 Evaluation board schematic diagram.
