LM4120

SNVS049F –FEBRUARY 2000–REVISED MARCH 2016

LM4120 Precision Micropower Low Dropout Voltage Reference

1 Features

3 Description

The LM4120 device is a precision low-power, low

dropout bandgap voltage reference with up to 5-mA

output current source and sink capability.

•

Small SOT23-5 Package

Low Dropout Voltage: 120 mV Typical at 1 mA

High Output Voltage Accuracy: 0.2%

Source and Sink Current Output: ±5 mA

Supply Current: 160 μA Typical

Low Temperature Coefficient: 50 ppm/°C

Enable Pin

This series reference operates with input voltages as

low as 2 V and up to 12 V, consuming 160-µA

(typical) supply current. In power-down mode, device

current drops to less than 2 μA.

The LM4120 comes in two grades (A and Standard)

and seven voltage options for greater flexibility. The

best grade devices (A) have an initial accuracy of

0.2%, while the standard have an initial accuracy of

0.5%, both with

50 ppm/°C ensured from −40°C to 125°C.

Fixed Output Voltages: 1.8, 2.048, 2.5, 3, 3.3,

4.096, and 5 V

•

Industrial Temperature Range: −40°C to 85°C

temperature coefficient of

(For Extended Temperature Range, −40°C to

125°C, Contact TI)

The very low dropout voltage, low supply current, and

power-down capability of the LM4120 make this

product an ideal choice for battery-powered and

portable applications.

2 Applications

•

Portable, Battery-Powered Equipment

Instrumentation and Process Control

Automotive and Industrial

Test Equipment

The device performance is ensured over the industrial

temperature range (−40°C to 85°C), while certain

specifications are ensured over the extended

temperature range (−40°C to 125°C). Contact TI for

full specifications over the extended temperature

range. The LM4120 is available in a standard 5-pin

SOT-23 package.
