Figure 7. Adjustable Linear Voltage Regulator
Figure 7 is similar to Figure 6 with adjustability added. Note the addition of R3. This is only required for the AP1117 due to the fact that its ground
or adjustment pin can only supply a few micro-amps of current at best. R3 is therefore needed to provide sufficient bias current for the TLV431.
