Improved Precision Micropower Shunt Voltage

Reference with Multiple Reverse Breakdown Voltages

General Description

Features

The LM4040 is a precision two-terminal shunt mode,

bandgap voltage reference available in fixed reverse

breakdown voltages of 2.048V, 2.500V, 3.000V, 4.096V,

and 5.000V. Ideal for space-critical applications, the

LM4040 is offered in the subminiature 3-pin SC70 sur-

ꢀ Ultra-Small 3-Pin SC70 Package

ꢀ 0.1% max Initial Accuracy

ꢀ 100ppm/°C max Temperature Coefficient

Guaranteed over -40°C to +85°C Temperature

Range

face-mount package (1.8mm 1.8mm), 50% smaller

than comparable devices in SOT23 surface-mount

packages (SOT23 versions are also available).

ꢀ Wide Operating Current Range: 60µA to 15mA

ꢀ Low 28µV

Output Noise (10Hz to 10kHz)

RMS

Laser-trimmed resistors ensure precise initial accuracy.

With a 100ppm/°C temperature coefficient, the device

is offered in four grades of initial accuracy ranging from

0.1% to 1%. The LM4040 has a 60µA to 15mA shunt

current capability with low dynamic impedance, ensur-

ing stable reverse breakdown voltage accuracy over a

wide range of operating temperatures and currents.

ꢀ 2.048V, 2.500V, 3.000V, 4.096V, and 5.000V Fixed

Reverse Breakdown Voltage

ꢀ No Output Capacitors Required

ꢀ Tolerates Capacitive Loads

The LM4040 does not require an external stabilizing

capacitor while ensuring stability with any capacitive

load.

For a 1.225V output version, refer to the LM4041 data

sheet.
