Description
The R5326X Series is a CMOS-based voltage regulator IC with high output voltage accuracy, low supply current, and improved transient response compared to conventional regulators. It consists of a voltage reference unit, an error amplifier, resistors for setting the output voltage, and a current limit circuit. The chip enable function allows for ultra low supply current in standby mode. The small packages make high density mounting on boards possible.
