PTCC AS432 1.24V Precision Adjustable Shunt Reference Datasheet
The AS432 is a three‑terminal adjustable shunt regulator that uses an accurate 1.24 V bandgap reference. It offers 0.25 %‑2.0 % bandgap tolerance, an internal amplifier capable of 150 mA, and low‑frequency dynamic output impedance below 150 mΩ. The device is designed for low‑voltage applications but can handle up to 18 V reverse breakdown and operates over a wide temperature range.
The datasheet provides absolute maximum ratings, recommended operating conditions, pin configurations for various packages (TO‑92, SOIC, SOT‑23, SOT‑89), and typical performance curves including voltage regulation, noise, and pulse response.
