Secondary Variable Output LDO Regulator Series for Local Power Supplies
300mA Secondary Variable Output
LDO Regulators for Local Power Supplies
BD00GA3WEFJ
No.10026EAT05
Description
BD00GA3WEFJ is a LDO regulator with output current 0.3A. 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.
Features
1) Output current 0.3A
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
