Texas Instruments REF33xx 3.9-μA, SC70-3, SOT-23-3, and UQFN-8, 30-ppm/°C Drift Voltage Reference, Part #REF3333AIDCKT | Reference | DEX

Texas Instruments REF33xx 3.9-μA, SC70-3, SOT-23-3, and UQFN-8, 30-ppm/°C Drift Voltage Reference, Part #REF3333AIDCKT | Reference | DEX 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: 1• 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) • High Initial Accuracy: ±0.15% (max) • 0.1-Hz to 10-Hz Noise: 35 μVPP (REF3312) • Voltage Options: 1.2 V, 1.8 V, 2.5 V, 3 V, 3.3 V

Applications: • Portable Equipment • Tablets and Smartphones • Hard Disk Drives • Sensor Modules • Data Acquisition Systems • Medical Equipment • Test Equipment
