R1161D321B-TR-F - Brand New RICOH IC Chips
-
Description
The R1161D321B-TR-F is a CMOS-based voltage regulator IC from the R1160x Series. It is designed with high output voltage accuracy, low supply current, and low ON-resistance. The IC consists of a voltage reference unit, an error amplifier, resistors for setting the output voltage, a current limit circuit, and a chip enable circuit. It operates with low dropout voltage and has a chip enable function to prevent destruction by over current. The R1161D321B-TR-F has three modes: standby mode with CE or standby control pin, Fast Transient Mode (FT mode), and Low Power Mode (LP mode) with ECO pin™. The consumption current is reduced to 1/10 in LP mode compared to FT mode. These ICs come in SOT-23-5 and SON-6 packages, allowing for high-density mounting on boards.
