MCP1525中文资料2.5V Voltage Reference数据手册Microchip规格书

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.

简介

MCP1525属于集成电路（IC）的电压基准。由制造生产的MCP1525电压基准产品属于基准电压源系列，可通过相对较不稳定的电源提供稳定的电势，电压值始终保持恒定，以便在测量、控制和类似应用中用作比较的标准。其功能行为可能与用于大功率调节的线性稳压器相似，但基准电压源器件却不适合用于此类用途。用作比较标准时，若输出电流容量或实际负载电流增大，其性能通常会降低。
