- Low-Voltage Operation, VREF = 1.24 V
- Adjustable Output Voltage, VO = VREF to 6V
- Reference Voltage Tolerances at 25°C – 0.5% for TLV431B – 1% for TLV431A – 1.5% for TLV431
- Packages: SOT-23
- SMD Marking: YACU
- 0.25-Ω Typical Output Impedance
TLV431ACDBZR Low-Voltage Adjustable Precision Shunt Regulator.
When used with an optocoupler, the TLV431 device is an ideal voltage reference in isolated feedback circuits for 3-V to 3.3-V switching-mode power supplies. These devices have a typical output impedance of 0.25 Ω. Active output circuitry provides a very sharp turnon characteristic, making them excellent replacements for low-voltage Zener diodes in many applications, including on-board regulation and adjustable power supplies.
Applications:-
- Adjustable Voltage and Current Referencing
- Secondary Side Regulation in Flyback SMPSs
- Voltage Monitoring
- Comparator With Integrated Reference
