It provides a very simple, low cost solution that uses very little pcb real estate. Additional features include an enable pin to allow for a P ≈(VIN− VOUT)• I D O very low power consumption standby mode, and a fully adjustable output. The absolute worst-case dissipation is given by: Component Selection ( ) P = VIN − VOUT • I + VIN • I D(MAX ) (MAX ) (MIN ) O (MAX ) (MAX ) Q (MAX ) Input capacitor: a 4.7µF ceramic capacitor is For a typical scenario, V = 3.3V ± 5%, V = 2.8V and IN OUT recommended. This allows for the device being some I = 1.5A, therefore: O distance from any bulk capacitance on the rail. Additionally, input droop due to load transients is reduced, V = 3.465V, V = 2.744V and I = 1.75mA, IN(MAX) OUT(MIN) Q(MAX) improving load transient response. Additional capacitance may be added if required by the application. Thus P = 1.09W.
