CJ431 Description

Short technical summary and product information.

The CJ431-TA is an adjustable accurate reference source from JIANGSU CHANGJIANG ELECTRONICS TECHNOLOGY CO., LTD. This voltage reference IC is designed for applications requiring precise voltage regulation. It features an adjustable output voltage that can be set from 2.5V up to 36V, with a maximum output current capability of 100mA. The device boasts a low dynamic output impedance, typically 0.2 Ω, and a typical equivalent temperature factor of 50 ppm/°C across its operating temperature range.

Key electrical characteristics include a reference input voltage typically around 2.495V with a maximum deviation over temperature of 17mV. The input current is low, typically 1.5 μA, with a deviation over temperature of 0.4 μA. The minimum cathode current required for regulation is 0.45mA, and the off-state cathode current is very low, typically 0.05 μA.

The CJ431-TA is available in a SOT-89 package, suitable for surface mounting. Its operating temperature range is specified from 0°C to 70°C, with a storage temperature range of -65°C to 150°C. The absolute maximum ratings include a cathode voltage of 37V and a continuous cathode current range of -100mA to +150mA.
