· Note

1. Please use this IC within the stated absolute maximum ratings.

The IC is liable to malfunction should the ratings be exceeded.

2. Due to restrictions on the package power dissipation, the output current value may not be satisﬁed.

Attention should be paid to the power dissipation of the package when the output current is large or the

voltage between Iinput and Output is high.

3. The output capacitor is required between output and GND to prevent oscillation.

4. The ESR of capacitor must be deﬁned in ESR stability area. It is possible to use a ceramic capacitor without

ESR resistance for output. The ceramic capacitor must be used more than 0.47µF and B temperature

characteristics.

5. The wire of VDD and GND is required to print full ground plane for noise and stability.

6. The input capacitor must be connected a distance of less than 1cm from input pin.

7. It is able to oscillation when you use the capacitor with intense capacitance change such as micro.

Please evaluate IC in the set.

8. In case the output voltage is above the input voltage, the overcurrent ﬂow by internal parastic diode from

output to input.In such application, the external bypass diode must be connected between output and input

pin.

9. This IC will limit the output current with the overcurrent protection circuit when the overcurrent and the

output do short-circuit.

However, IC generates heat because of the substrate and use conditions and there is a possibility of

destroying it exceeding a permissible loss.

The characteristic changes depending on the substrate condition. Please evaluate IC in the set.

It is recommended to layout the VIA for heat radiation in the GND pattern of reverse (of IC) when there is the

GND pattern in the inner layer (in using multiplayer substrate).

By increasing these copper foil pattern area of PCB, Power dissipation improves.
