AUTOMOTIVE COMPLIANT ADJUSTABLE PRECISION SHUNT REGULATOR
Description
Pin Assignments
The ZTL431AQ, ZTL431BQ, ZTL432AQ and ZTL432BQ 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.
(Top View)
The ZTL432AQ, ZTL432BQ has the same electrical specifications as
the ZTL431AQ, ZTL431BQ but has a different pin out in SOT23 (F-
suffix) and SOT23F (FF-suffix).

(ZTL431AQ, ZTL431BQ)
(Top View)
The ZTL431AQ, ZTL431BQ, ZTL432AQ and ZTL432BQ are
available in 2 grades with initial tolerances of 1% and 0.5% for the A
and B grades respectively.
These are functionally equivalent to the TL431/TL432 except for
maximum operation voltage, and have an ambient temperature range
of -40°C to +125°C as standard.
SOT23, SOT23F
(ZTL432AQ, ZTL432BQ)
The ZTL431AQ, ZTL431BQ, ZTL432AQ and ZTL432BQ are qualified
to AEC-Q100 Grade 1 and are Automotive Compliant supporting
PPAPs.

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

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 ZTL431AQ, ZTL431BQ, ZTL432AQ and ZTL432BQ 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.
