Secondary LDO Regulator Series for Local Power Supplies
500mA Secondary LDO Regulators
for Local Power Supplies
BD□□KA5,BD□□KA5W Series,BD00KA5W Series
No.09024EAT01
●General Description
The BD□□KA5 series are low-saturation regulators that are available for output currents up to 500mA. The output voltage
precision is ±1%. These secondary 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
1) Maximum output current : 500ｍA
2) Output voltage precision : ±1%
3) Low-saturation voltage with PMOS output : 0.12V Typ.(Io=200mA)
4) Built-in over-current protection circuit
5) Built-in thermal shutdown circuit
6) Shutdown switch(BD□□KA5WFP and BD□□KA5WF series)
7) TO252-3,TO252-5 and SOP8 package lineup
8) Operating temperature range : -40℃ to +105℃
9) Ceramic capacitor compatible(recommended capacitance : 1μF or greater)
●Applications
Microcontrollers and all electronic devices that use logic circuits
