TL43, B Series, NC43, B Series, SC43 Programmable Precision References The TL43, B integrated circuits are threeterminal programmable shunt regulator diodes. These monolithic IC voltage references operate as a low temperature coefficient zener which is programmable from ref to 36 with two external resistors. These devices exhibit a wide operating current range of. m to m with a typical dynamic impedance of.22. The characteristics of these references make them excellent replacements for zener diodes in many applications such as digital voltmeters, power supplies, and op amp circuitry. The 2.5 reference makes it convenient to obtain a stable reference from 5. logic supplies, and since the TL43, B operates as a shunt regulator, it can be used as either a positive or negative voltage reference.

TL43, B Series, NC43, B Series, SC43 PPLICTIONS INFORMTION The TL43 is a programmable precision reference which is used in a variety of ways. It serves as a reference voltage in circuits where a nonstandard reference voltage is needed. Other uses include feedback control for driving an optocoupler in power supplies, voltage monitor, constant current source, constant current sink and series pass regulator. In each of these applications, it is critical to maintain stability of the device at various operating currents and load capacitances. In some cases the circuit designer can estimate the stabilization capacitance from the stability boundary conditions curve provided in Figure 5. However, these typical curves only provide stability information at specific cathode voltages and at a specific load condition. dditional information is needed to determine the capacitance needed to optimize phase margin or allow for process variation. simplified model of the TL43 is shown in Figure 3. When tested for stability boundaries, the load resistance is 5. The model reference input consists of an input transistor and a dc emitter resistance connected to the device anode. dependent current source, Gm, develops a current whose amplitude is determined by the difference between the.78 internal reference voltage source and the input transistor emitter voltage. portion of Gm flows through compensation capacitance, C P2. The voltage across C P2 drives the output dependent current source, Go, which is connected across the device cathode and anode. Model component values are: ref =.78 Gm =.3 + 2.7 exp (I C /26 m) where I C is the device cathode current and Gm is in mhos Go =.25 ( cp 2) mhos. Resistor and capacitor typical values are shown on the model. Process tolerances are ± 2% for resistors, ±% for capacitors, and ±4% for transconductances. n examination of the device model reveals the location of circuit poles and zeroes: P 7.96 khz 2 R C 2 *. M * 2 pf GM P P2 Z 6 khz 2 R C 2 * M *.265 pf P2 P2 5 khz 2 R C 2 *5.9k*2pF Z P In addition, there is an external circuit pole defined by the load: P L 2 R C L L lso, the transfer dc voltage gain of the TL43 is: Example : G G M R GM GoR L I C m, R L 23,C L. Define the transfer gain. The DC gain is: G G M R GM GoR L (2.38)(. M)(.25 )(23) 65 56 db Loop gain G 8.25 k 28 47 db 8.25 k 5 k The resulting transfer function Bode plot is shown in Figure 32. The asymptotic plot may be expressed as the following equation: jf 5 khz v 65 jf jf 8. khz 6 khz The Bode plot shows a unity gain crossover frequency of approximately 6 khz. The phase margin, calculated from the equation, would be 55.9 degrees. This model matches the OpenLoop Bode Plot of Figure 2. The total loop would have a unity gain frequency of about 3 khz with a phase margin of about 44 degrees.

Cathode tied to reference input pin. n examination of the data sheet stability boundary curve (Figure 5) shows that this value of load capacitance and cathode current is on the boundary. Define the transfer gain. The DC gain is: G G M R GM GoR L (2.323)(. M)(.25 )(22) 6389 76 db The resulting open loop Bode plot is shown in Figure 33. The asymptotic plot may be expressed as the following equation: jf 5 khz v 65 jf jf jf 8. khz 6 khz 7.2 khz Note that the transfer function now has an extra pole formed by the load capacitance and load resistance. Note that the crossover frequency in this case is about 25 khz, having a phase margin of about 46 degrees. Therefore, instability of this circuit is likely. v, OPEN-LOOP GIN (db) 8 6 4 2-2 TL43 OPEN-LOOP BODE PLOT WITH LOD CP 2 3 4 5 6 f, FREQUENCY (Hz) Figure 33. Example 2 Circuit Open Loop Gain Plot With three poles, this system is unstable. The only hope for stabilizing this circuit is to add a zero. However, that can only be done by adding a series resistance to the output capacitance, which will reduce its effectiveness as a noise filter. Therefore, practically, in reference voltage applications, the best solution appears to be to use a smaller value of capacitance in low noise applications or a very large value to provide noise filtering and a dominant pole rolloff of the system. 2
