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.
