GENERAL DESCRIPTION
The ADR390 and ADR391 are precision 2.048 V and 2.5 V
bandgap voltage references featuring high accuracy and stability
and low power consumption in a tiny footprint. Patented temperature
drift curvature correction techniques minimize nonlinearity of the
voltage change with temperature. The wide operating range and
low power consumption with additional shutdown capability
make them ideal for 3 V to 5 V battery-powered applications.
The V
OUT
Sense Pin enables greater accuracy by supporting full
Kelvin operation in systems using very fine or long circuit traces.
The ADR390 and ADR391 are micropower, Low Dropout Voltage
(LDV) devices that provide a stable output voltage from supplies as
low as 300 mV above the output voltage. They are specified over the
industrial (–40
°
C to +85
°
C) temperature range. Each is available
in the tiny 5-lead SOT-23 package.
The combination of V
OUT
sense and shutdown functions also
enables a number of unique applications combining precision
reference/regulation with fault decision and overcurrent protec-
tion. Details are provided in the Applications section.
