Overview
The TLV431ALPRMG is a low voltage precision adjustable shunt regulator manufactured by onsemi. It features a programmable output voltage range from 1.24 V to 16 V and an initial reference accuracy of ±1.0% at 25 °C for the A series. The device operates within a temperature range of -40 °C to 85 °C, with a maximum cathode-to-anode voltage of 18 V and a continuous cathode current range of -20 mA to 25 mA. It utilizes a TO-92-3 package (LP suffix) and is supplied in an ammo pack configuration.
Feature Summary
- Programmable output voltage range spanning 1.24 V to 16 V
- Guaranteed reference accuracy of ±1.0% at 25 °C
- Sharp low current turn-on characteristic with low dynamic impedance
- Wide operating current range from 50 µA to 20 mA
Applications
- Low output voltage switching power supply error amplifier
- Adjustable voltage or current linear and switching power supplies
- Voltage monitoring circuits
- Current source and sink applications
- Low voltage zener diode replacements
Procurement Notes
Verify the specific ordering suffix 'MG' corresponds to the Ammo Pack shipping format as documented in the official onsemi datasheet. Confirm that the component meets Pb-Free and Halide-Free requirements. Ensure design compatibility with the TO-92-3 package dimensions and pinout configuration specified for the LP suffix variant.
Selection Notes
Select this component when a precise, adjustable shunt regulator is required for low voltage applications. The A series offers standard accuracy suitable for general-purpose regulation. Consider the thermal resistance characteristics of the TO-92-3 package for heat dissipation needs. Verify that the operating current range aligns with the circuit's minimum and maximum load requirements.
Part Context
This part belongs to the TLV431 family of low voltage precision adjustable shunt regulators. It serves as a direct replacement for traditional Zener diodes in circuits demanding higher precision and stability. The device integrates an internal bandgap reference and error amplifier to regulate the cathode-to-anode voltage based on the reference input.
