Application Notes

Notes: 1. CIN and COUT must be located as close as possible to the IC to stabilize IC operation.

2. COUT must be 0.1µF or larger, and a capacitor (such as a tantalum capacitor) with a low temperature

coefficient must be used to prevent oscillation at low temperatures.

3. If the STB pin is open, the internal bias will result in the output going to the on state. If the STB function is not

used, the STB pin must be connected to ground to complete the STB operation.

4. Note that a large current will flow if the IC is connected in reverse, that is, if VIN is connected to - and GND is

connected to +.
