描述 Description

MCP1525 is a low power, high precision voltage reference. It provides a precise output voltage of 2.5V which is then compared to other voltages in the system.This voltage reference is normally used in the 3V to 5V systems, where there may be wide variations in supply voltage and a need to minimize power dissipation. This devices use a combination of an advanced CMOS circuit design and EEPROM trimming to provide and an initial tolerance of 1% (max) and temperature stability of 50ppm/C (max). This device is offered in SOT23-3 & TO-92 packages and is ideal for communications equipment, data acquisition systems, instrumentation and process control, high precision power supplies and battery powered equipment.

簡介

MCP1525屬于集成電路（IC）的電壓基準。由制造生產(chǎn)的MCP1525電壓基準產(chǎn)品屬于基準電壓源系列，可通過相對較不穩(wěn)定的電源提供穩(wěn)定的電勢，電壓值始終保持恒定，以便在測量、控制和類似應用中用作比較的標準。其功能行為可能與用于大功率調(diào)節(jié)的線性穩(wěn)壓器相似，但基準電壓源器件卻不適合用于此類用途。用作比較標準時，若輸出電流容量或實際負載電流增大，其性能通常會降低。
