TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The LM341 and LM78Mxx devices are fixed voltage regulators meaning no external feedback resistors are required to set the output voltage. Input and output capacitors are also not required for the device to be stable. However input capacitance helps filter noise from the supply and output capacitance improves the transient response. 8.2 Typical Application *Required if regulator input is more than 4 inches from input filter capacitor (or if no input filter capacitor is used). **Optional for improved transient response. Figure 11. Typical Application 8.2.1 Design Requirements For this design example, use the parameters listed in Table 1 as the input parameters. Table 1. Design Parameters PARAMETER VALUE CIN 0.33 µF COUT 0.1 µF 8.2.2 Detailed Design Procedure 8.2.2.1 Input Voltage Regardless of the output voltage option being used (5 V, 12 V, 15 V), the input voltage must be at least 2 V greater to ensure proper regulation (7 V, 14 V, 17 V). |
