Design a Custom BoardMicropower precision voltage reference IC with fixed 3.3V output and ±1% accuracy over 0–100°C temperature range. Supplies up to 20mA with excellent line and load regulation, input range 4.2–28V, and operates stably without output capacitors. Includes short-circuit and reverse input protection; ideal for precision regulators, data acquisition, and portable instrumentation.
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.
