GENERAL DESCRIPTION
The ADR130 is the industry’s first family of tiny, micropower,
low voltage, high precision voltage references. Featuring 0.35%
initial accuracy and 25 ppm/°C of temperature drift in the tiny
TSOT-23 package, the ADR130 voltage reference only requires
80 μA for typical operation. The ADR130 design includes a
patented temperature drift curvature correction technique that
minimizes the nonlinearities in the output voltage vs. temperature characteristics.
Available in the industrial temperature range of −40°C to
+125°C, the ADR130 is housed in a tiny TSOT package.
For 0.5 V output, tie SET (Pin 5) to V
(Pin 4). For 1.0 V
OUT
output, tie SET (Pin 5) to GND (Pin 2).

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, a device
soldered in a circuit board for surface-mount packages.
