Description
The R1170H331B-T1 is a positive voltage regulator IC by CMOS process. It is part of the R1170 Series, which is known for its high ripple rejection, low dropout voltage, high output voltage accuracy, and low consumption current. This IC consists of a voltage reference unit, an error amplifier, resistor net for setting output voltage, a current limit circuit at short mode, a chip enable circuit, and thermal-shunt circuit. The output voltage of the R1170 is fixed in the IC. It offers low consumption current thanks to the CMOS process and built-in transistors with low ON-resistance, resulting in low dropout voltage and prolonged battery life. The R1170 series also excels in terms of ripple rejection, input transient response, and load transient response. Despite its compact size, it can handle a large maximum output current, making it suitable for various power sources in portable appliances. The IC is available in SOT-89-5 package or HSON6, allowing high-density mounting on boards.
