DESCRIPTION

The CAT102 is a low-voltage reference and amplifier. Designed for the control loop of low-voltage power supplies, the reference voltage has been designed for 600 mV. Over a temperature from -40°C to 85°C, the reference voltage is within 8 mV of the nominal 600mV. In addition, the error amplifier output and the supply voltage pin (IN) are on separate pins.

FEATURES

■ 600 mV low voltage reference

CAT102TDI-G属于集成电路（IC） > 电压基准。安森美半导体公司制造生产的CAT102TDI-G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。
