The small package size and high operating frequency of the LT1616 result in a very small circuit size. In most applications, the LT1616 circuit will occupy less space than a linear regulator performing the same task and will dissipate much less power. This requires a TO-220 style package and either moving air or a heat sink to get rid of the heat. Figure 4 compares the size of the LT1616 solution with a TO-220 package. 2.5V Output Figure 5 shows a 2.5V output circuit using the LT1616.
All components are surface mount types.
The load current on the positive output should be larger than the load on the negative output. For a more complete description of this circuit, see Linear Technology Design Note 100. Adapter A very common power source for small electronic systems is the AC adapter or wall transformer. There are many advantages to powering a product from one of these cubes. They are an inherently safe and inexpensive way to plug into 120V outlets.
