Secondary Variable Output LDO Regulator Series for Local Power Supplies
1A Secondary Variable Output
LDO Regulators for Local Power Supplies
BD00GC0WEFJ
No.10026EAT08
●Description BD00GC0WEFJ is a LDO regulator with output current 1.0A. 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 1.0A 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
