Higher Current Shunt Regulator. Must be electrically isolated from the.

The output voltage may be set at any level. Minimum Cathode Current for Regulation.

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. Also the current draw by op-amp and resistor network is neglected for easy explanation.

Pin Configuration LM has three pins and function of each pin is mentioned below. It is a 3-terminal shunt regulator with guaranteed temperature stability over the entire temperature range of operation.


Life support devices or systems are devices or. LM can be configured in many application circuits and a few are stated in the datasheet. The output voltage may be set at any level greater than 2.

Single Supply Comparator with. To ensure that the geometry of the micro SMD package. When the device is programmed with two datashdet resistors, R1 and R2, see Figure 2the dynamic output impedance of the overall circuit, r Zis defined as: Dynamic Impedance vs Frequency. When the transistor turns ON the device draws current and because of this current drawing a voltage drop appears across R1 resistor which is in series with voltage source V1.

Infrared or Convection 20 sec. Here reference voltage Vref is the voltage at the non-inverting terminal of the op-amp and this voltage determines whether the op-amp outputs positive voltage or not. C, the SO-8 at 6. Electrical specifications do not apply when operating the device.

Dynamic Output Impedance Note 6.

Adjustable Precision Zener Shunt Regulator. TL — Programmable Reference Voltage.

Current Limiter or Current Source. Submitted by admin on 18 November LM is a regulator IC featured with adjustable output voltage. Above this temperature, derate the TO at 6. V Z from 10V to 36V. Whenever the output crosses threshold threshold is value determined by R2 and R3 value the op-amp get feedback via Vref and datashret drives the transistor Datasneet. C unless otherwise specified.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. A critical component is any component of a life.

Symbol and Functional Diagrams. Absolute Maximum Ratings Note 2. Deviation of Reference Input Voltage Over. C, slope is positive. Output Control of a Three. So in the final result Vo will always be adjusted to float near the measured value by op-amp setup or LM
