YAC6 SMD Low-Voltage Adjustable Precision Shunt Regulator || YAC6 Transistor SMD || YACU Transistor.

Description :

The TLV431ACDBZRG4 device is a low-voltage 3-terminal adjustable voltage reference with specified thermal stability over applicable industrial and commercial temperature ranges. Output voltage can be set to any value between VREF (1.24 V) and 6 V with two external resistors (see the Parameter Measurement Information section). These devices operate from a lower voltage (1.24 V) than the widely used TLV431ACDBZRG4 (YAC6) and TLV431ACDBZR (YACU) shunt-regulator references.

When used with an optocoupler, the TLV431ACDBZRG4 (YAC6) 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.

Features :
