Sink Current Capability, 1mA to 100mA
Low Reference Pin Current
The LT1431 is an adjustable shunt voltage regulator with
100mA sink capability, 0.4% initial reference voltage tol-
erance, and 0.3% typical temperature stability. On-chip
dividerresistorsallowtheLT1431tobeconfiguredasa5V
shunt regulator, with 1% initial voltage tolerance and
requiring no additional external components. By adding
twoexternalresistors,theoutputvoltagemaybesettoany
value between 2.5V and 36V. The nominal internal current
limit of 100mA may be decreased by including one exter-
nal resistor.

COLL (Pin 1): Open collector of the output transistor. The
maximum pin voltage is 26V. The saturation voltage at
100mA is approximately 1V.
RMID (Pin 7): Middle of the on-chip resistive divider string
between RTOP and GND-S. The pin is tied to REF for self-
contained 5V operation. It may be left open if unused.
COMP (Pin 2): Base of the driver for the output transistor.
This pin allows additional compensation for complex
feedback systems and shutdown of the regulator. It must
be left open if unused.
V+ (Pin 3): Bias voltage for the entire shunt regulator. The
maximum input voltage is 36V and the minimum to
operate is equal to VREF (2.5V). The quiescent current is
typically 0.6mA.
REF (Pin 8): Control pin of the shunt regulator with a 2.5V
threshold. If V+ > 3V, input bias current cancellation
reduces IB to 0.2µA typical.
COMP, RTOP, RMID, and REF have static discharge protec-
tion circuits that must not be activated on a continuous
basis. Therefore, the absolute maximum DC voltage on
these pins is 6V, well beyond the normal operating condi-
tions.
RTOP (Pin 4): Top of the on-chip 5k-5k resistive divider
that guarantees 1% accuracy of operation as a 5V shunt
regulator with no external trim. The pin is tied to COLL for
self-contained 5V operation. It may be left open if unused.
See note on parasitic diodes below.
As with all bipolar ICs, the LT1431 contains parasitic
diodes which must not be forward biased or else anoma-
lous behavior will result. Pin conditions to be avoided are
R
TOP below RMID in voltage and any pin below GND-F in
voltage (except for GND-S).
GND-S (Pin 5): Ground reference for the on-chip resistive
divider and shunt regulator circuitry except for the output
transistor. This pin allows external current limit of the
output transistor with one resistor between GND-F (force)
and GND-S (sense).
The following pin definitions apply to the Z package.
CATHODE (Pin 1): Corresponds to COLL and V+ tied
together.
ANODE (Pin 2): Corresponds to GND-S and GND-F tied
together.
GND-F (Pin 6): Emitter of the output transistor and sub-
strate connection for the die.
REF (Pin 3): Corresponds to REF.

Frequency Compensation
pole-zero compensation. This can be accomplished with a
capacitor or series resistor and capacitor between COLL
and COMP.
Asashuntregulator, theLT1431isstableforallcapacitive
loads on the COLL pin. Capacitive loading between 0.01µF
and18µFcausesreducedphasemarginwithsomeringing
under transient conditions. Output capacitors should not
be used arbitrarily because output noise is not necessarily
reduced.
The compensation schemes mentioned above use voltage
feedback to stabilize the circuits. There must be voltage
gain at the COLL pin for them to be effective, so the COLL
pin must see a reasonable AC impedance. Capacitive
loading of the COLL pin reduces the AC impedance,
voltage gain, and frequency response, thereby decreasing
the effectiveness of the compensation schemes, but also
decreasing their necessity.
Excess capacitance on the REF pin can introduce enough
phase shift to induce oscillation when configured as a
reference >2.5V. This can be compensated with capaci-
tance between COLL and REF (phase lead). More compli-
cated feedback loops may require shaping of the fre-
quency response of the LT1431 with dominant pole or
