Design a Custom BoardAdjustable precision shunt regulator with 1% voltage tolerance and programmable output from 1.24V to 18V using two external resistors. Features low temperature coefficient (20ppm/°C), low dynamic output resistance (0.05Ω), and sink current capacity up to 100mA. Ideal for switching power supplies, chargers, and voltage regulation applications.
SOT-23's tiny 0.95mm pin pitch and compact form factor make hand-soldering tedious and prone to bridging errors. A breakout board breaks out the three pins to standard 0.1" spacing for breadboard prototyping, eliminating the need for specialized soldering equipment and enabling fast circuit iteration with transistors, diodes, and small-signal components.
