2 / 15 page Typical Application (Continued) Connection Diagram and Package Mark Information Pin Descriptions Pin # Name Description 1V IN Power supply input. Connect to the input filter capacitor ( Figure 1). 2 GND Ground pin. 3 EN Enable input. The device is in shutdown mode when voltage to this pin is <0.4V and enable when >1.0V. Do not leave this pin floating. 4 FB Feedback analog input. Connect to the output filter capacitor for fixed voltage versions. For adjustable version external resistor dividers are required ( Figure 2). The internal resistor dividers are disabled for the adjustable version. 5 SW Switching node connection to the internal PFET switch and NFET synchronous rectifier. 20167230 FIGURE 2. Typical Application Circuit SOT23-5 Package NS Package Number MF05A 20167202 Note: The actual physical placement of the package marking will vary from part to part. FIGURE 3.
