LM431SACM3X onsemi / Fairchild

Here is the English description of the LM431SACM3X chip:

• Function: Precision Adjustable Shunt Regulator
• Output Voltage: Adjustable from 1.2V to 30V
• Current Limit: 100mA
• Temperature Range: -40°C to 125°C
• Package: SOT-23-3

The LM431SACM3X is an adjustable precision shunt regulator from Texas Instruments.

Key Features:

• Output voltage programmable with an external resistor
• Low quiescent current of 30μA
• SOT-23-3 miniature package saves space
• Wide operating temperature range

Common Applications:

• Adjustable linear regulators requiring 1.2-30V reference
• Circuits requiring accurate and stabilized reference voltage
• Portable/battery-powered devices with size constraints

Benefits include a very accurate and customizable voltage reference. Small size enables integration into space-constrained designs.

Well-suited as a reference regulator for adjustable linear/switching regulators, instrumentation circuits and comparators where programming voltage is important.

In summary, the LM431SACM3X provides a precisely adjustable 1.2-30V reference with flexibility and very low quiescent current in a miniature package.
