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.
