Test Circuit for Off-State Current. Now let us consider a simple application circuit for the device as shown below: Above this temperature, derate the TO at 6. Ratings apply to ambient temperature at 25? Distributors for availability and specifications. Before going for application circuit of LMlet us first understand the internal working of the device and for that consider the functional diagram of the device as shown below.

AN for more detailed information regarding board. Electrical specifications do not apply when operating the device.

Dynamic Impedance vs Frequency. Deviation of Reference Input Voltage Over. Test Circuit for Curve A Above. Here Ic is the current drawn by the transistor.


Absolute Maximum Ratings Note 2. It popular application include. A critical component is any component of a life. Also the current draw by op-amp and resistor network is neglected for easy explanation.

Deviation of Reference Input Current over. LM is a regulator IC featured with adjustable output voltage. Internal Power Dissipation Notes 3, 4. To ensure that the geometry lm4331 the micro SMD package. Minimum Cathode Current for Regulation.

Must be electrically isolated from the.

Whenever the output crosses threshold threshold is value determined by R2 and R3 value the op-amp get feedback via Vref and it drives the transistor ON. The LM is a 3-terminal adjustable shunt regulator with. C, slope is positive. Submitted by admin on 18 November Due to the l431 turn-on characteristics this device is an excellent replacement for many zener diode applications.

Output Control of a Three. C unless otherwise specified. V Z from 10V to 36V. National does not assume any responsibility for use of any circuitry described, no circuit patent licenses are implied and National reserves the right at any time without notice to change said circuitry and specifications.
