LM4120 Precision Micropower Low Dropout Voltage Reference

Check for Samples: LM4120

FEATURES

DESCRIPTION

The LM4120 is a precision low power low dropout

• Small SOT23-5 Package

bandgap voltage reference with up to 5 mA output

• Low Dropout Voltage: 120 mV Typ @ 1 mA

current source and sink capability.

• High Output Voltage Accuracy: 0.2%

This series reference operates with input voltages as

• Source and Sink Current Output: ±5 mA

low as 2V and up to 12V consuming 160 µA (Typ.)

• Supply Current: 160 μA Typ.

supply current. In power down mode, device current

drops to less than 2 μA.

• Low Temperature Coefficient: 50 ppm/°C

The LM4120 comes in two grades (A and Standard)

• Enable Pin

and seven voltage options for greater flexibility. The

• Fixed Output Voltages: 1.8, 2.048, 2.5, 3.0, 3.3,

best grade devices (A) have an initial accuracy of

4.096 and 5.0V

0.2%, while the standard have an initial accuracy of

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

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 Texas Instruments)

The very low dropout voltage, low supply current and

power-down capability of the LM4120 makes this
