7.2 Typical Applications

TL1963A TL1963A-15 TL1963A-18 TL1963A-25 TL1963A-33 Adjustable Output Voltage Operation
A. All capacitors are ceramic.
Figure 7-1 Adjustable Output Voltage Operation

Use the TL1963A-xx in a fixed voltage configuration. Connect the SENSE/ADJ pin to OUT for proper operation as in Figure 7-2. For a fixed output voltage of 1.21V, use the TL1963A.
