LM4132, LM4132-Q1

SNVS372G –AUGUST 2005–REVISED OCTOBER 2016

LM4132, LM4132-Q1 SOT-23 Precision Low Dropout Voltage Reference

1 Features

3 Description

The LM4132 family of precision voltage references

performs comparable to the best laser-trimmed

bipolar references, but in cost-effective CMOS

technology. The key to this breakthrough is the use of

EEPROM registers for correction of curvature,

temperature coefficient (tempco), and accuracy on a

CMOS band-gap architecture allowing package-level

programming to overcome assembly shift. The shifts

in voltage accuracy and tempco during assembly of

die into plastic packages limit the accuracy of

references trimmed with laser techniques.

•

Qualified for Automotive Applications

•

AEC-Q100 Qualified With the Following Results:

–

Device Temperature Grade 1: –40ºC to

+125ºC Ambient Operating Temperature

Range

–

Device HBM ESD Classification Level 2

•

Output Initial Voltage Accuracy: 0.05%

Low Temperature Coefficient: 10 ppm/°C

Low Supply Current: 60 µA

Enable Pin Allowing a 3-µA Shutdown Mode

20-mA Output Current

Unlike other LDO references, the LM4132 can deliver

up to 20 mA and does not require an output capacitor

or buffer amplifier. These advantages along with the

SOT-23 packaging are important for space-critical

applications.

Voltage Options: 1.8 V, 2.048 V, 2.5 V, 3 V,

3.3 V, 4.096 V

•

Custom Voltage Options Available

(1.8 V to 4.096 V)

Series references provide lower power consumption

than shunt references, because they do not have to

idle the maximum possible load current under no-load

conditions. This advantage, the low quiescent current

(60 µA), and the low dropout voltage (400 mV) make

the LM4132 ideal for battery-powered solutions.

•

V_INRange of V_REF+ 400 mV to 5.5 V at 10 mA

Stable With Low-ESR Ceramic Capacitors

2 Applications

The LM4132 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 a specified

temperature coefficient of 10 ppm/°C or less, while

the lowest grade devices (E) have an initial accuracy

of 0.5% and a tempco of 30 ppm/°C.
