500mA Secondary LDO Regulators for Local Power Supplies

ROHM Semiconductor 

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
