500mA Variable/Fixed Output
LDO Regulators
BDxxKA5 Series BDxxKA5W Series BD00KA5W Series
General Description
The BDxxKA5 series are low-saturation regulators that are available for output currents up to 500mA. 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.

Be sure to place an anti-oscillation capacitor between the output terminal and the GND. Oscillations may arise if the
capacitance value changes, due to factors such as temperature changes. A 1μF capacitor with small internal series resistance
(ESR) such as a ceramic capacitor is recommended as an anti-oscillation capacitor. Ceramic capacitors generally have
favorable temperature characteristics and DC bypass characteristics. When selecting a ceramic capacitor, a high voltage
capacitor (good DC bypass characteristics) with temperature characteristics that are superior to those of X5R or X7R, is
recommended. In applications where input voltage and load fluctuations are rapid, please decide on a capacitor after
sufficiently confirming its properties according to its specifications in the actual application.
