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

●About Input-to-output capacitor
It is recommended that a capacitor is placed nearby pin between Input pin and GND, output pin and GND.
A capacitor, between input pin and GND, is valid when the power supply impedance is high or drawing is long. Also as for a
capacitor, between output pin and GND, the greater the capacity, more sustainable the line regulation and it makes improvement
of characteristics by load change. However, please check by mounted on a board for the actual application. Ceramic capacitor
usually has difference, thermal characteristics and series bias characteristics, and moreover capacity decreases gradually by
using conditions.
For more detail, please be sure to inquire the manufacturer, and select the best ceramic capacitor.
