MCP1525/41 devices are 2.5V and 4.096V precision voltage references that Output Voltages: 2.5V and 4.096V use a combination of an advanced CMOS circuit Initial Accuracy: 1% (max.) design and EPROM trimming to provide an initial Temperature Drift: 50 ppm/C (max.) tolerance of 1% (max.) and temperature stability of Output Current Drive: 2 mA 50ppm/C (max.). In addition to a low quiescent Maximum Input Current: 100 A +25C (max.) current of 100 A (max.) at 25C, these devices offer a clear advantage over the traditional Zener techniques Packages: TO-92 and SOT-23-3 in terms of stability across time and temperature. The Industrial Temperature Range: -40C to +85C output voltage is 2.5V for the MCP1525 and 4.096V for the MCP1541. These devices are offered in SOT-23-3 Applications and TO-92 packages, and are specified over the industrial temperature range of -40C to +85C.

The 85C output voltage is then again trimmed to zero out the tempco. 2: Output Voltage Hysteresis is defined as the change in output voltage measured at +25C before and after cycling the temperature to +85C and -40C refer to Section 1.1.10 Output Voltage Hysteresis.
