INDUCTOR
An LDO is connected in series at the output of the switching power supply to obtain a
more stable power supply. Figure 2-7 shows this circuit. Microchip's MCP1701 device
and MCP1700 device, low drop-out high efficiency LDOs, are selected for use.
D301 is the power LED for the meter and is active when the meter is connected to the
proper line input voltage.
