REF31xx-Q1 15 ppm/°C Maximum, 100-µA, SOT-23 Series Voltage Reference

1 Features

3 Description

The REF31xx-Q1 is a family of precision, low power,

low dropout, series voltage references available in the

tiny 3-pin SOT-23 package.

•

AEC-Q100 Qualified With the Following Results:

–

Device T_ARange: –40°C to 125°C

Device HBM ESD Classification Level H1C

Device CDM ESD Classification Level C4A

The REF31xx-Q1 small size and low power

consumption (100 μA typical) make it ideal for

portable and battery-powered applications. The

REF31xx-Q1 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.

•

High Accuracy: 0.2% Maximum

Excellent Specified Drift Performance:

–

20 ppm/°C (Maximum) from –40°C to +125°C

•

High Output Current: ±10 mA

Low Dropout: 5 mV

Unloaded, the REF31xx-Q1 can operate on supplies

down to 5 mV above the output voltage. All models

are specified for the wide temperature range of –40°C

to +125°C.

Low I_Q: 115 µA Maximum

Low Noise: 17 µVp-p/V

No Output Capacitor Required
