SPX29301集成电路（IC）的线性+开关稳压器规格书PDF中文资料

DESCRIPTION

The SPX29300/01/02/03 are 3A, highly accurate voltage regulators with a low drop out voltage of 450mV dropout (typical) @ 3A. These regulators are specifically designed for low voltage applications that require a low dropout voltage and a fast transient response. They are fully fault protected against over-current, reverse battery, and positive and negative voltage transients. On-Chip trimming adjusts the reference voltage to 1 initial accuracy. Other features in the 5 pin versions include Enable, and Error Flag.
