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.
●Features
Output voltage precision: ±1%
Low-saturation voltage with PMOS output: 0.12V
Typ.(Io=200mA)
Built-in over-current protection circuit
Built-in thermal shutdown circuit
Shutdown switch (BDxxKA5WFP and BDxxKA5WF
series)
Ceramic capacitor compatible (recommended
capacitance: 1μF or greater)
