NSREF3140：High-precision, Low-tempco, Low-noise, Low-power Voltage Reference
The NSREF3140 is a family of precision, low power, low dropout, series voltage references available in the tiny 3-pin SOT23 package. The NSREF3140's small size and low power consumption make it ideal for portable and battery-powered applications. The NSREF3140 does not require a load capacitor, but is stable with any capacitive load and can sink or source up to ±10 mA of output current. Unloaded, the NSREF3140 can operate on supplies down to 1 mV above the output voltage. All models are specified for the wide temperature range of -40°C to +125°C.
