Overview
The TL431KLP-AP is a programmable shunt voltage reference integrated circuit manufactured by Micro Commercial Components (MCC). It operates within a supply voltage range of 2.5V to 36V and provides an output current capability of 100mA. The device features a typical output impedance of 0.2Ω and maintains thermal stability across an operating temperature range of -40°C to 85°C. It is housed in a TO-92-3 (TO-226AA) through-hole package, designed for precise voltage regulation and reference applications.
Feature Summary
- Programmable output voltage adjustable between 2.5V and 36V via external resistors
- Low output impedance for stable performance in shunt regulator configurations
- Thermal stability maintained across extended commercial temperature ranges
Applications
- Board-level voltage regulation
- Adjustable power supplies
- Switching power supply feedback loops
- Zener diode replacement circuits
Procurement Notes
Verify the specific suffix 'AP' against official MCC documentation to confirm pinout compatibility and tolerance specifications. Ensure the TO-92 package variant matches your PCB footprint requirements. Cross-reference with authorized distributors to confirm current availability status, as component lifecycles may vary.
Selection Notes
Select this component when a low-cost, through-hole programmable reference is required for general-purpose linear or switching regulator designs. Consider the 100mA current limit and TO-92 thermal dissipation characteristics relative to your load requirements. Verify that the 2.5V to 36V adjustment range covers your target output voltage needs.
Part Context
This part belongs to the widely adopted TL431 family of three-terminal adjustable shunt regulators. These devices are standard components in power management ICs, offering a cost-effective solution for voltage referencing and control loop compensation in various electronic systems.
Replacement Considerations
Compatible substitutes include the TL431AILP and TL431ACLP from Texas Instruments, which share similar electrical characteristics and TO-92 packaging. Ensure functional equivalence regarding reference voltage accuracy and operating temperature range before substitution.
