Datasheet 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 0A 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.
