8.3 Power Supply Recommendations

This device is designed to operate from an input supply voltage range of 1.5 V to 6.0 V. The input supply must

be well regulated and free of spurious noise. To ensure that the output voltage is well regulated and dynamic

performance is optimum, the input supply must be at least VOUT(nom) + 0.5 V. TI highly recommends using a 1-µF

or greater input capacitor to reduce the impedance of the input supply, especially during transients.

8.4 Layout

8.4.1 Layout Guidelines

• Place input and output capacitors as close to the device as possible.

• Use copper planes for device connections to optimize thermal performance.

• Place thermal vias around the device to distribute the heat.

• Do not place a thermal via directly beneath the thermal pad of the DQN package. A via can wick solder or

solder paste away from the thermal pad joint during the soldering process, leading to a compromised solder

joint on the thermal pad.
