TS821中文资料1.225V微功耗分流器电压参考数据手册ST规格书

描述 Description

The TS821 is a low power shunt voltage reference providing a stable 1.225V output voltage over the industrial temperature range (-40°C to +85°C). Availabe in SOT23-3 surface mount package, it can be designed in applications where space saving is critical.

The low operating current is a key advantage for power restricted designs. In addition, the TS821 is very stable and can be used in a broad range of application conditions.

特性 Features

• 120ppm/°C maximum temperature coefficient
• 1.225V typical output voltage
• High precision @ 25°C+/- 2% (standard version)+/- 1% (A grade)+/- 0.5% (B grade)
• Ultra low operating current: 45μA maximum at 25°C
• Industrial temperature range: -40°C to +85°C
• High stability when used with capacitive loads

简介

TS821属于集成电路（IC）的电压基准。由ST制造生产的TS821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。
