Questions buyers ask
- Can AiP431 replace TL431?
- AiP431 is I-CORE's functional equivalent of TL431 in the same SOT-23 package. Standard parts in this family share the industry pinout, but please compare both datasheets — supply range, timing and absolute maximum ratings — before design-in.
- What is the supply voltage and temperature range of AiP431?
- Supply: See datasheet. Operating temperature: −40 to 85 °C. See the datasheet for full electrical characteristics.
- Is AiP431 in stock, and can I get a free sample?
- Yes, it is held in stock in Shenzhen. Free samples are available for evaluation, with shipping paid by us. For production orders, SMD parts can be ordered from 1 pc and DIP parts ship in full tubes; orders ship within 2–3 business days after payment.
- Is it original I-CORE product?
- Yes. We supply factory-original I-CORE (Wuxi I-CORE Electronics) parts in sealed reels and tubes. Our ISO 9001, ISO 14001 and ISO 45001 certificates are shown on the home page; RoHS and REACH test reports are available on request.
Datasheet highlights
From the I-CORE English datasheet AiP431 (revision 2026-04-B4). The full datasheet PDF is linked above.
General description
AiP431-AiP432 is a three terminal adjustable parallel regulator with guaranteed thermal stability over applicable extended commercial temperature ranges. It can set the output voltage through two external resistors between Vref (about 2.5V) and 36V any value. It also features a typical output impedance of 0.2Ω. AiP431/ AiP432 is an excellent adjustable replacement for Zener diodes in many applications such as operational amplifier circuits, adjustable power supplies, and switching power supplies. The AiP432 offers identical functionality and electrical characteristics to the AiP431, but with a different pin configuration.
