SNVS238A –MAY 2004–REVISED APRIL 2013

LM4125 Precision Micropower Low Dropout Voltage Reference

Check for Samples: LM4125

FEATURES

DESCRIPTION

The LM4125 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 Typ @ 1 mA

High Output Voltage Accuracy: 0.2%

Source and Sink Current Output: ±5 mA

Supply Current: 160 μA Typ.

This series reference operates with input voltages as

low as 2V and up to 6V consuming 160 µA (Typ.)

supply current. In power down mode, device current

drops to less than 2 μA.

Low Temperature Coefficient: 50 ppm/°C

Fixed Output Voltages: 2.048, 2.5,and 4.096

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

The LM4125 comes in two grades (A and Standard)

and three 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 a tempco of 50ppm/°C ensured from

−40°C to +125°C.

(For Extended Temperature Range, −40°C to

125°C, Contact TI)

APPLICATIONS

The very low dropout voltage, low supply current and

power-down capability of the LM4125 makes this

product an ideal choice for battery powered and

portable applications.

Test Equipment

The device performance is ensured over the industrial

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

specs are ensured over the extended temperature

range (−40°C to +125°C). Please contact TI for full

specifications over the extended temperature range.

The LM4125 is available in a standard 5-pin SOT-23

package.
