LM4431
www.ti.com SNVS103C – JUNE 2000 – REVISED APRIL 2013 LM4431 Micropower Shunt Voltage Reference
Check for Samples: LM4431 FEATURES DESCRIPTION Ideal for space critical applications, the LM4431
voltage reference is available in the sub-miniature
(3 mm x 1.3 mm) SOT-23 surface-mount package.
The LM4431's advanced design eliminates the need
for an external stabilizing capacitor while ensuring
stability with any capacitive load, thus making the
LM4431 easy to use. The operating current range is
100 ОјA to 15 mA. 1 2 Small Package: SOT-23
No Output Capacitor Required
Tolerates Capacitive Loads
Fixed Reverse Breakdown Voltage of 2.50V APPLICATIONS Portable, Battery-Powered Equipment
Data Acquisition Systems
Instrumentation
Process Control
Energy Management
Product Testing
Power Supplies The LM4431 utilizes fuse and zener-zap reverse
breakdown voltage trim during wafer sort to ensure
that the parts have an accuracy of better than В±2.0%
at 25В°C. Bandgap reference temperature drift
curvature correction and low dynamic impedance …
