SNOS455E –MAY 2000–REVISED APRIL 2013

LM4050-N/LM4050-N-Q1 Precision Micropower Shunt Voltage Reference

Check for Samples: LM4050-N, LM4050-N-Q1

FEATURES

DESCRIPTION

Ideal for space critical applications, the LM4050-N

•

Small Package: SOT-23

precision voltage reference is available in the sub-

miniature (3 mm x 1.3 mm) SOT-23 surface-mount

package. The LM4050-N design eliminates the need

for an external stabilizing capacitor while ensuring

stability with any capacitive load, thus making the

LM4050-N easy to use. Further reducing design effort

is the availability of several fixed reverse breakdown

voltages: 2.048V, 2.500V, 4.096V, 5.000V, 8.192V,

and 10.000V. The minimum operating current

increases from 60 μA for the LM4050-N-2.0 to 100

μA for the LM4050-N-10.0. All versions have a

maximum operating current of 15 mA.

No Output Capacitor Required

Tolerates Capacitive Loads

Fixed Reverse Breakdown Voltages of 2.048V,

2.500V, 4.096V, 5.000V, 8.192V, and 10.000V

APPLICATIONS

•

Portable, Battery-Powered Equipment

Data Acquisition Systems

Instrumentation

Process Control

The LM4050-N utilizes fuse and zener-zap reverse

breakdown voltage trim during wafer sort to ensure

that the prime parts have an accuracy of better than

±0.1% (A grade) at 25°C. Bandgap reference
