1 / 35 page LM4050-N, LM4050-N-Q1 www.ti.com SNOS455E – MAY 2000 – REVISED APRIL 2013 LM4050-N/LM4050-N-Q1 Precision Micropower Shunt Voltage Reference Check for Samples: LM4050-N, LM4050-N-Q1 1 FEATURES DESCRIPTION Ideal for space critical applications, the LM4050-N 2 • Small Package: SOT-23 precision voltage reference is available in the sub- • No Output Capacitor Required miniature (3 mm x 1.3 mm) SOT-23 surface-mount • Tolerates Capacitive Loads package. The LM4050-N design eliminates the need for an external stabilizing capacitor while ensuring • Fixed Reverse Breakdown Voltages of 2.048V, stability with any capacitive load, thus making the 2.500V, 4.096V, 5.000V, 8.192V, and 10.000V LM4050-N easy to use. Further reducing design effort is the availability of several fixed reverse breakdown APPLICATIONS voltages: 2.048V, 2.500V, 4.096V, 5.000V, 8.192V, • Portable, Battery-Powered Equipment and 10.000V. The minimum operating current increases from 60 μA for the LM4050-N-2.0 to 100 • Data Acquisition Systems μA for the LM4050-N-10.0. All versions have a • Instrumentation maximum operating current of 15 mA. • Process Control The LM4050-N utilizes fuse and zener-zap reverse • Energy Management breakdown voltage trim during wafer sort to ensure • Product Testing that the prime parts have an accuracy of better than ±0.1% (A grade) at 25°C. Bandgap reference • Automotive temperature drift curvature correction and low • Precision Audio Components dynamic impedance ensure stable reverse breakdown voltage accuracy over a wide range of KEY SPECIFICATIONS (LM4050-N-2.5) operating temperatures and currents. • Output Voltage Tolerance (A grade, 25°C) All grades and voltage options of the LM4050-N are ±0.1% (max) available in both an industrial temperature range ( −40°C and +85°C) and an extended temperature • Low Output Noise (10 Hz to 10 kHz) 41 range ( −40°C and +125°C). μVrms(typ) • Wide Operating Current Range 60 μA to 15 mA CONNECTION DIAGRAM • Industrial Temperature Range −40°C to +85°C • Extended Temperature Range −40°C to +125°C • Low Temperature Coefficient 50 ppm/°C (max) • LM4050-N-Q1A/-Q1B/-1QC are AECQ100 Grade 1 Qualified and are Manufactured on an Automotive Grade Flow *This pin must be left floating or connected to pin 2.
