TS432/432A/432B
Adjustable Precision Shunt Regulator
Sink Current Capability up to 100mA
General Description
The TS432/432A/432B is a three-terminal adjustable shunt regulator with specified thermal stability. The output voltage
may be set to any value between Vref (approximately 1.24V) and 18V with two external resistors. The TS432/432A/432B
has a typical output impedance of 0.2Ω. Active output circuitry provides a very sharp turn-on characteristic, making the
TS432/432A/432B excellent replacement for zener diode in many applications.
This series is offered in 3-pin TO-92, SOT-89, SOT-23 and 5-pin SOT-25 package.

Note 4. Deviation of reference input voltage, VDEV, is defined as the maximum deviation of the reference over the full
temperature range.
The average temperature coefficient of the reference input voltage αVref is defined as:
| αVref | = [ VDEV / Vref(25) ] * 106 / T2 – T1…………………….. (PPM/ oC)
Where: T2-T1 = full temperature change.
αVref can be positive or negative depending on whether the slope is positive or negative.
Note 5. The dynamic output impedance, Rz, is defined as:
| Zka | = ∆Vka / ∆Ika
When the device is programmed with two external resistors R1and R2 (see Figure 2). The dynamic output
impedance of the overall circuit, is defined as :
| Zka | = ∆v / ∆i | ≈ Zka | * ( 1 + R1 / R2)
