MCP1501
High-Precision Buffered Voltage Reference
Features General Description • Maximum Temperature Coefficient: 50 ppm/°C
from –40°C to +125°C
• Initial Accuracy: 0.1%
• Operating Temperature Range: –40 to +125°C
• Low Typical Operating Current: 140 μA
• Line Regulation: 50 ppm/V Maximum
• Load Regulation: 40 ppm/mA Maximum
• 8 Voltage Variants Available:
-1.024V
-1.250V
-1.800V
-2.048V
-2.500V
-3.000V
-3.300V
-4.096V
• Output Noise: 27 µVRMS, 10 Hz to 10 kHz
(1.024V) The MCP1501 is a buffered voltage reference capable
of sinking and sourcing 20 mA of current. The voltage
reference is a low-drift bandgap-based reference. The
bandgap uses chopper-based amplifiers, effectively
reducing the drift to zero.
The MCP1501 is available in the following packages:
• 6-Lead SOT-23
• 8-Lead SOIC
• 8-Lead 2 mm x 2 mm WDFN Package Types
