BD00GA5WEFJ
Signal
1) Output current 0.5A
2) High accuracy reference voltage circuit
3) Built-in Over Current Protection circuit (OCP)
4) Built-in Thermal Shut Down circuit (TSD)
5) With shut down switch
6) Output voltage variable type (1.5V to 13.0V)
7) Package: HTSOP-J8
BD00GA5WEFJ is a LDO regulator with output current 0.5A. The output accuracy is ±1% of output voltage. With
external resistance, it is available to set the output voltage at random (from 1.5V to 13.0V) and also provides output
voltage fixed type without external resistance. It is used for the wide applications of digital appliances. It has package
type: HTSOP-J8. Over current protection (for protecting the IC destruction by output short circuit), circuit current
ON/OFF switch (for setting the circuit 0μA at shutdown mode), and thermal shutdown circuit (for protecting IC from heat
destruction by over load condition) are all built in. It is usable for ceramic capacitor and enables to improve smaller set
and long-life.

... BD00GA5WEFJ (11). Regarding input pin of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of these P layers with the N layers of other elements, creating a parasitic diode or transistor. For example, the relation between each potential is as follows: When GND > ...
