Improved Precision Micropower

Shunt Voltage Reference

General Description

Features

The LM4041 is a precision two-terminal shunt mode,

bandgap voltage reference with a fixed reverse break-

down voltage of 1.225V. Ideal for space-critical appli-

cations, the LM4041 is offered in the subminiature 3-pin

♦ Ultra-Small 3-Pin SC70 Package

♦ 0.1% (max) Initial Accuracy

♦ 100ppm/°C (max) Temperature Coefficient

Guaranteed over -40°C to +125°C Temperature

Range

SC70 surface-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 12mA

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 LM4041 has a 60µA to 12mA shunt

current capability with low dynamic impedance, ensur-

ing stable reverse-breakdown voltage accuracy over a

wide range of operating temperatures and currents.

♦ Low 20µV

Output Noise (10Hz to 10kHz)

RMS

♦ 1.225V Fixed Reverse Breakdown Voltage

♦ No Output Capacitors Required

♦ Tolerates Capacitive Loads

Ordering Information

The LM4041 does not require an external stabilizing

capacitor while ensuring stability with any capacitive

load.
