R1170H341B-T1-FB - Brand New RICOH IC Chips
-
Description
The R1170H341B-T1-FB is a positive voltage regulator IC that is part of the R1170 Series. These ICs are manufactured using the CMOS process and have various features such as high ripple rejection, low dropout voltage, high output voltage accuracy, and low consumption current. The R1170H341B-T1-FB consists of a voltage reference unit, an error amplifier, resistor net for setting the output voltage, a current limit circuit at short mode, a chip enable circuit, and a thermal-shunt circuit. It is designed to have a fixed output voltage and is suitable for use in portable appliances. The ICs are available in SOT-89-5 or HSON6 packages, allowing for high density mounting on boards.
