International Semiconductor's LIv13 34 is a three-terminal regulator. You can use an external power
supply to set the current of I+= 66.7×1 0- 3/RSET. For example, RSET=6.8Q
~ 68 k0, you can get 1UA ~ lOmA. Constant current, adjustment rate is
0. oz"-/v.
Specific application examples include: using a voltage above 3. sv to set a low current bandgap
reference voltage diode. If the operating current is above 10"A, then determine the constant current
The current adjustment resistor Ri of the circuit can be calculated by the following
formula: Other applications include: used to set the operating current of the programmable OP amplifier
, and can also be used in sawtooth wave generating
circuits, deflection limiters, and external diodes
. A tube-mounted reference voltage generator
, etc. Can be widely used for constant current device
