Low Power Consumption LDO 6209 Series

General Description 

The 6209 series are a group of positive voltage output, three –pin regulator, that provide a high current even when the input/output Voltage differential is small. Low power consumption and high accuracy is achieved through CMOS technology. They allow input voltages as high as 18V. 

Typical Application 

Cameras, video recorders

Voltage regulator for microprocessor

Voltage regulator for LAN cards

 (VIN= VOUT+1.0V，CIN=CL=10uF，Ta=25OC, unless otherwise noted)

Note ：

1.V_OUT (T) ：Specified Output Voltage 

2.V_OUT (E) ：Effective Output Voltage ( ie. The output voltage when “V_OUT (T)+ 1.0V”is provided at the Vin pin while 

                      maintaining a certain I_OUT value.) 

3.V_DIF：V_IN1 –V_OUT (E)’ 

             V_IN1：The input voltage when V_OUT(E)’ appears as input voltage is gradually decreased. 

             V_OUT (E)’=A voltage equal to 98% of the output voltage whenever an amply stabilized I_OUT and {V_OUT (T)+ 1.0V}

             is  input. 

Precautions 

1.During the test, if AC/DC power supply and the ceramic chip capacitors collocation are used, there may be serious voltage spike phenomenon instantaneously. When the power supply access to 16V, the voltage is rushed to about 30V instantaneously. Because of exceeding the limit voltage of chip, the chip is damaged. If you string a small resistance of 1 ohm in the input end during the test, the peak phenomenon can be avoided. 

2. In the test, there is serious burr phenomenon only when the AC/DC power is used with ceramic chip capacitors. But electrolytic capacitors and tantalum capacitance won't appear above phenomenon. Please be sure to pay attention to this point when you use AC/DC power.

3.In normal use, when any type of capacitor is used with battery or the supply of fire power, the above phenomenon doesn’t occur.
