Deviation of Reference Input Voltage Over.

The dynamic output impedance, r Zis defined as: Datasheett Limiter or Current Source. Test Circuit for Curve A Above. It is a 3-terminal shunt regulator with guaranteed temperature stability over the entire temperature range of operation. Electrical specifications do not apply when operating the device.

TL — Programmable Reference Voltage. In a similar way we can setup other application circuits.

The LM is a 3-terminal adjustable shunt regulator with. LM can be configured in many application circuits and a few are stated in the datasheet. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.


C, the SO-8 at 6. Deviation of reference input voltage, V DEVis defined as the maximum variation of the reference input voltage over the full temperature range.

The output voltage may be set at any level greater than 2. C, slope is positive.

Symbol and Datasheeet Diagrams. 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.

Minimum Cathode Current for Regulation. The output voltage may be set at any level. Input Current vs V Z. The areas under the curves represent conditions that may cause datashheet device to oscillate. 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.


Due to the sharp turn-on characteristics this device is an excellent replacement for many zener diode applications. It is now available in a chip sized pack.

A critical component is any component of a life. Now let us consider a simple application circuit for the device as shown below: So in the final result Vo will always be adjusted to float near the measured value by op-amp setup or LM Dynamic Output Impedance Note 6. Higher Current Shunt Regulator.
