Description
The Microchip Technology Inc. MCP1525/41 devices
are 2.5V and 4.096V precision voltage references that
use a combination of an advanced CMOS circuit
design and EPROM trimming to provide an initial
tolerance of ±1% (max.) and temperature stability of
±50 ppm/°C (max.). In addition to a low quiescent
current of 100 µA (max.) at 25°C, these devices offer a
clear advantage over the traditional Zener techniques
in terms of stability across time and temperature. The
output voltage is 2.5V for the MCP1525 and 4.096V for
the MCP1541. These devices are offered in SOT-23-3
and TO-92 packages, and are specified over the
industrial temperature range of -40°C to +85°C.

Note 1: Output temperature coefficient is measured using a “box” method, where the +25°C output voltage is trimmed as close
to typical as possible. The 85°C 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 +25°C before and after cycling the
temperature to +85°C and -40°C; refer to Section 1.1.10 “Output Voltage Hysteresis”.
