500m A Variable/Fixed Output LDO Regulators BDxx KA5 Series BDxx KA5W Series BD00KA5W Series ●General Description The BDxx KA5 series are low-saturation regulators that are available for output currents up to 500m A. The output voltage precision is ±1%. These LDO regulators are offered in several output voltages and package lineups with or without ON/OFF switches (that set the circuit current to 0μA at shutdown). This series can be used for a broad spectrum of applications ranging from TVs and car audio systems to HDDs, PCs, and DVDs. There regulators have a built-in overcurrent protection circuit that prevents the destruction of the IC, due to output short circuits and a thermal shutdown circuit.

Frequently Asked Questions
What protection features does the regulator offer?
It includes a built-in overcurrent protection circuit to prevent IC destruction and a thermal shutdown circuit.
How do I completely switch off the output current?
Use the dedicated shutdown switch (WFP or WF series), which sets the circuit current to 0μA in OFF mode.
What is the maximum operating current and input voltage?
The maximum output current capacity is 500mA, and the input power supply voltage must not exceed 5.5V.
Is there a required capacitance for stable operation?
Yes, it requires a ceramic capacitor compatible with recommended capacitance of 1μF or greater.
