The REF29xx small size and low power consumption (50 µA max) make it ideal for portable and battery-powered applica- tions. The REF29xx does not require a load capacitor, but is stable with any capacitive load. Unloaded, the REF29xx can be operated with supplies within 1mV of output voltage. All models are specified for the wide temperature range, –40 °C to +125°C. FEATURES q MicroSIZE PACKAGE: SOT23-3 q LOW DROPOUT: 1mV q HIGH OUTPUT CURRENT: 25mA q LOW TEMPERATURE DRIFT: 100ppm/ °C max q HIGH ACCURACY: 2% q LOW I Q: 50µA max PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.
