MAX6138
PRODUCTION0.1%, 25ppm, SC70 Shunt Voltage Reference with Multiple Reverse Breakdown Voltages
- Part Models
- 38
- 1ku List Price
- Starting From $2.03
Overview
- Ultra-Small 3-Pin SC70 Package
- 0.1% (max) Initial Accuracy
- 25ppm/°C (max) Temperature Coefficient Guaranteed Over -40°C to +85°C Temperature Range
- Wide Operating Current Range: 60µA to 15mA
- Low 28µVRMS Output Noise (10Hz to 10kHz)
- 1.2205V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V Fixed Reverse Breakdown Voltages
- No Output Capacitors Required
- Stable with Capacitive Loads
The MAX6138 is a precision, two-terminal shunt mode, bandgap voltage reference available in fixed reverse breakdown voltages of 1.2205V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V. Ideal for space-critical applications, the MAX6138 is offered in the subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm), 50% smaller than comparable devices in SOT23 surface-mount packages.
Laser-trimmed resistors ensure precise initial accuracy. With a 25ppm/°C temperature coefficient, the device is offered in three grades of initial accuracy ranging from 0.1% to 0.5%. The MAX6138 has a 60µA to 15mA shunt-current capability with low-dynamic impedance, ensuring stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents.
The MAX6138 does not require an external stabilizing capacitor while ensuring stability with capacitive loads. The MAX6138 is a higher precision device in a smaller package than the LM4040/LM4050.
