LM4050BEX3-2.1+T Datasheet(HTML) 1 Page - Maxim Integrated Products |
1 / 13 page General Description The LM4050/LM4051 are precision two-terminal, shunt- mode, bandgap voltage references available in fixed reverse breakdown voltages of 1.225V, 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. Ideal for space-criti- cal applications, the LM4050/LM4051 are offered in the subminiature 3-pin SC70 surface-mount packages (1.8mm x 1.8mm), 50% smaller than comparable devices in SOT23 surface-mount package (SOT23 ver- sions are also available). Laser-trimmed resistors ensure excellent initial accuracy. With a 50ppm/°C temperature coefficient, these devices are offered in three grades of initial accu- racy ranging from 0.1% to 0.5%. The LM4050/LM4051 have a 60µA to 15mA shunt-current capability with low dynamic impedance, ensuring stable reverse break- down voltage accuracy over a wide range of operating temperatures and currents. The LM4050/LM4051 do not require an external stabilizing capacitor while ensuring stability with any capacitive loads. The LM4050/LM4051 specifications are guaranteed over the temperature range of -40°C to +125°C. ________________________Applications Portable, Battery-Powered Equipment Notebook Computers Cell Phones Industrial Process Controls Features ♦ 50ppm/°C (max) Temperature Coefficient Guaranteed over the -40°C to +125°C Temperature Range ♦ Ultra-Small 3-Pin SC70 Package ♦ 0.1% (max) Initial Accuracy ♦ Wide Operating Current Range: 60µA to 15mA ♦ Low 28µVRMS Output Noise (10Hz to 10kHz) ♦ 1.225V, 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V Fixed Reverse Breakdown Voltages ♦ No Output Capacitors Required ♦ Tolerates Capacitive Loads 50ppm/°C Precision Micropower Shunt Voltage References with Multiple Reverse Breakdown Voltages ________________________________________________________________ Maxim Integrated Products 1 - 1 3 N.C.* + LM4050/ LM4051 SC70/SOT23 TOP VIEW 2 *PIN 3 MUST BE LEFT FLOATING OR CONNECTED TO PIN 2.
