Due to the sharp turn-on characteristics this device is an excellent replacement for many zener diode applications. Also Vref is the voltage at the midpoint voltage divider network formed by the two resistors R2 and R3.

Ratio of the Change in Reference Voltage. 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.

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

National Semiconductor

Internal Power Dissipation Notes 3, 4. Deviation of reference input voltage, V DEVis defined as the maximum variation of the reference input voltage over the full temperature range. A critical component is any component of a life. It popular application include.

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: Dstasheet Cathode Current for Regulation. TL — Programmable Reference Voltage.
