Figure 29. Typical Application

power supply considerations

The TPS201x family has multiple inputs and outputs, which must be connected in parallel to minimize voltage

drop and prevent unnecessary power dissipation.

A 0.047-

µF to 0.1-µF ceramic bypass capacitor between IN and GND, close to the device, is recommended.

A high-value electrolytic capacitor is also desirable when the output load is heavy or has large paralleled

capacitors. Bypassing the output with a 0.1-

µF ceramic capacitor improves the immunity of the device to

electrostatic discharge (ESD).
