R1170H331A-T1-F - Brand New RICOH IC Chips
-
Description
The R1170H331A-T1-F is a low-dropout voltage regulator integrated circuit (IC) that provides a fixed output voltage. This product is suitable for various power sources for portable appliances and is designed with features such as high ripple rejection, low dropout voltage, high output voltage accuracy, and low consumption current. It 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 R1170H331A-T1-F comes in a small SOT-89-5 package or HSON6, which allows high density mounting on boards.
