REF3333 (ACTIVE)

30ppm/°C Drift, 3.9µA, SOT23-3, SC70-3, UQFN-8 Voltage Reference

 

Description

The REF33xx is a low-power, precision, low-dropout voltage reference family available in tiny SC70-3 and SOT-23-3 packages, and in a 1.5-mm × 1.5-mm UQFN-8 package. Small size and low power consumption (5-µA max) make the REF33xx ideal for a wide variety of portable and battery-powered applications.

The REF33xx can be operated at a supply voltage 180 mV above the specified output voltage under normal load conditions, with the exception of the REF3312, which has a minimum supply voltage of 1.7 V. All models are specified for the wide temperature range of –40°C to +125°C.

Features

  • Microsize Packages: SC70-3, SOT-23-3, UQFN-8
  • Low Supply Current: 3.9 µA (typ)
  • Extremely Low Dropout Voltage: 110 mV (typ)
  • High Output Current: ±5 mA
  • Low Temperature Drift: 30 ppm/°C (max)
