LM4130

Precision Micropower Low Dropout Voltage Reference

General Description

Features

n Small SOT23-5 package

n High output voltage accuracy

n Low Temperature Coefficient

n Stable with capacitive loads to 100µF

n Low dropout voltage

The LM4130 family of precision voltage references performs

comparable to the best laser-trimmed bipolar references, but

in cost effective CMOS technology. Key to this break through

is the use of EEPROM registers for correction of curvature,

tempco, and accuracy on a CMOS bandgap architecture that

allows package level programming to overcome assembly

shift. The shifts in voltage accuracy and tempco during as-

sembly of die into plastic packages limit the accuracy of ref-

erences trimmed with laser techniques.

Unlike other LDO references, the LM4130 requires no output

capacitor. Neither is a buffer amplifier required, even with

loads up to 20mA. These advantages and the SOT23 pack-

aging are important for cost-critical and space-critical appli-

cations.

Series references provide lower power consumption than Applications Summary

shunt references, since they don’t have to idle the maximum

possible load current under no load conditions. This advan-

tage, the low quiescent current (75µA), and the low dropout

voltage(275mV) make the LM4130 ideal for battery-powered

solutions.

The LM4130 is available in five grades (A, B, C, D and E) for

greater flexibility. The best grade devices (A) have an initial

accuracy of 0.05% with guaranteed temperature coefficient

of 10ppm/˚C or less, while the lowest grade parts (E) have

an initial accuracy of 0.5% and a tempco of 30ppm/˚C.
