Both devices combine a single step-down converter with two low-dropout (LDO) regulators. The stepdown converter enters a low-power mode at light load for maximum efficiency across the widest possible range of load currents. For low-noise applications, the devices can be forced into fixed-frequency PWM through a pin. The step-down converter is small because of its small inductor and capacitors. The step-down convert...
