The example of Application Circuit
*Output
*Thermal shutdown function
*Output short circuit detection function
*Output over voltage detection function
This product outputs 5V(±0.2V) from the terminal V
In VIN=2.7V~3.0V, it becomes 50mA or more. In VIN=3.0V or more, it becomes 100mA or more.
The thermal shutdown circuit works when the junction temperature exceeds 150℃(standard),
and IC stops operating.
(This function is not included in the product inspection.)
When the output do short-circuit, IOUT is limited to 250mA(standard).
The output is clamped so that VOUT should not become 6V or more even when the LED load is opened.
