说明

产品概览

The TL431AIDBZR from Texas Instruments is a programmable shunt voltage reference with 2.495V internal reference, +/-1% initial accuracy, and 1-100mA cathode current range in a SOT-23-3 package. The A-grade provides standard accuracy at the lowest cost.

Initial Accuracy +/-1% (A grade)
Temperature Drift 14 mV max over -40 to +85°C
Cathode Current Range 1 mA to 100 mA
Reference Input Current 2 uA typical
Dynamic Impedance 0.2 Ohm typical
工作温度 -40°C to +85°C
包装 SOT-23-3

特点

  • A-grade TL431 with +/-1% accuracy at lowest cost in SOT-23-3
  • Programmable output from 2.495V to 36V with 0.2 Ohm dynamic impedance

应用

  • Cost-sensitive SMPS feedback and general-purpose voltage reference

The TL431AIDBZR from Texas Instruments is the A-grade (standard accuracy) version of the industry-standard TL431 programmable shunt voltage reference in a SOT-23-3 package. The A grade provides +/-1% initial accuracy at 25°C, which is sufficient for the majority of SMPS feedback and voltage monitoring applications where the highest precision is not required. The device features the same 2.495V internal bandgap reference, programmable output from 2.495V to 36V using two external resistors, 0.2 Ohm dynamic impedance, and 1-100mA cathode current range as the higher-accuracy grades. The A grade is the most cost-effective option and is the highest-volume shipped version of the TL431 family. The I suffix indicates the industrial temperature range (-40°C to +85°C).

Identical to the TL431ACDBZR. The A grade provides +/-1% initial accuracy (vs +/-0.5% for AC/BC/CC grades) at a lower cost. All other operational characteristics are the same. See TL431ACDBZR entry for complete working principle.
