The board contains a number of test points to allow evaluating the functions of the ZSPM4141 (see Figure 2.1 and section 4). It has a solid ground plane on the back of the board. Note: The default part number for the ZSPM4141 Ultra-low-Power Linear Regulator (U1 in Figure 6.1) is the ZSPM4141AI1W12 (note 1), which is factory configured for V set to 1.2 V. If the application requires different OUT values for V , see section 5.2 for procedures for modifying V by changing resistor values on the board using OUT OUT the resistor set included with the kit. Note: The default resistor configuration for the Evaluation Board is with the FB pin pulled up to Vout via R1, which has a value of 0.0 (i.e., a short), and R2 is unpopulated (NL designation in the schematic in Figure 6.1).
