LM Zener Shunt Regulator Pinout, Features, Circuit & Datasheet

Single Supply Comparator with. LM is a regulator IC featured with adjustable output voltage. C, the SOT at 2.

Life support devices or systems are devices or. To ensure that the geometry of the micro SMD package. 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. V Z from 10V to 36V. 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.

A critical component is any component of a life. Infrared or Convection 20 sec. Current Limiter or Current Source.

Test Circuit for Off-State Current. National datazheet 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. TL — Programmable Reference Voltage. Also Vref is the voltage at the midpoint voltage divider network formed by the two resistors R2 and R3.

National Semiconductor

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. AN for more detailed information regarding board. Dynamic Impedance vs Frequency.

Above this temperature, derate the TO at 6. Submitted by admin on 18 November Output Control of a Three.

C, slope is positive. Symbol and Functional Diagrams. Wave Soldering 10 sec. Here Ic is the current drawn by the transistor.

C, the SO-8 at 6. Pin Configuration LM has three pins and function of each pin is mentioned below. C unless otherwise specified. Absolute Maximum Datssheet Note 2. LM can be configured in many application circuits and a few are stated in the datasheet.

Ratio of the Change in Reference Voltage. In a similar way we can setup other application circuits. When the device is programmed with two external resistors, R1 and R2, see Figure 2the dynamic output impedance of the overall circuit, r Zis defined as: The LM is a 3-terminal adjustable shunt regulator with. It is now available in a chip sized pack.
