Description

The LM431SA / LM431SB / LM431SC are three−terminal the output adjustable regulators with thermal stability over operating temperature range. The output voltage can be set any value between VREF (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 Ω. Active output circuit provides a sharp turn−on characteristic, making these devices excellent replacement for zener diodes in many applications.

Features

• Programmable Output Voltage to 36 V

• Low Dynamic Output Impedance: 0.2 Ω (Typical)

• Sink Current Capability: 1.0 to 100 mA

• Equivalent Full−Range Temperature Coefficient of 50 ppm/°C (Typical)

• Temperature Compensated for Operation Over Full Rated Operating Temperature Range

• Low Output Noise Voltage

• Fast Turn−on Response

• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant

LM431SBCMFX属于集成电路（IC） > 电压基准。安森美半导体公司制造生产的LM431SBCMFX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。
