ZTL431xQ/ZTL432xQ
AUTOMOTIVE COMPLIANT ADJUSTABLE PRECISION SHUNT REGULATOR
Description
Pin Assignments
The ZTL431xQ and ZTL432xQ are three terminal adjustable shunt
regulators offering excellent temperature stability and output current
handling capability up to 100mA. The output voltage may be set to
any chosen voltage between 2.5 and 20 volts by selection of two
external divider resistors.

Caution: Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings
only; functional operation of the device at conditions between maximum recommended operating conditions and absolute maximum ratings is not
implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time.
(Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling

DC Test Circuits
Notes
Deviation of reference input voltage, VDEV, is defined as the
maximum variation of the reference input voltage over the full
temperature range.
The average temperature coefficient of the reference input
voltage, VREF is defined as:
VREF(ppm/°C)
=
VDEV 1,000,000
VREF(T1-T2)
The dynamic output impedance, RZ, is defined as:
RZ = ΔVZ
ΔIZ
When the device is programmed with two external resistors, R1
and R2, (figure 2), the dynamic output impedance of the overall
circuit, R'Z, is defined as:
R'Z = RZ (1 + R1 )
R2
Stability Boundary
The ZTL431xQ and ZTL432xQ are stable with a range of
capacitive loads. A zone of instability exists as demonstrated in
the typical characteristic graph on Page 4. The graph shows
typical conditions. To ensure reliable stability, a capacitor of
4.7nF or greater is recommended between anode and
cathode.
