•
•
•
•
•
•
Wide Input Voltage Range (1V to 12V)
Operating Current From 100µA to 10mA
Ultra compact SOT23-3 Package
Initial Accuracy: ±1%
Low Dynamic Output Resistance of 0.5Ω
Stable With No External Capacitor
Temperature Range: –40°C to +85°C
The MP8200 is a low voltage (1.0V), precision
shunt regulator. It is offered in both fixed
versions. It can operate from 1V to 12V, giving
designers outstanding flexibility in the
development
of
power
supplies
and
instrumentation. The operating current of 100uA
makes the part well suited for battery-powered
portable electronic applications. The 8200
regulates the output voltage from as low as 1V.
The part has a sharp turn-on characteristic and
a dynamic resistance of less than 0.5Ω.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on approximately 1” square of 1 oz copper.

APPLICATION INFORMATION
External Bias Resistor
Output Voltage Trim
In the case of shunt voltage references, an
Using a mechanical or digital potentiometer, the
output voltage of the MP8200 can be trimmed
to ±0.5%. See Figure 2. Note that trimming
other resistor values may not produce an
accurate output from the MP8200.
external bias resistor (RBIAS
)
is required
between the supply voltage and the MP8200.
RBIAS sets the current that is required to pass
through the load and the IC.
V
CC
The load and supply voltages can vary, so RBIAS
should be chosen such that is it small enough
to supply the minimum current to the MP8200
when the supply voltage is at its minimum and
the load current is at its maximum. In addition,
RBIAS needs to be large enough that the
quiescent current does not exceed 10mA when
the supply voltage is at its maximum and the
load current is at its minimum.
