R1161D301B-TR-FA - Brand New RICOH IC Chips
-
Description
The R1161D301B-TR-FA is a CMOS-based voltage regulator IC with high output voltage accuracy, low supply current, and low ON-resistance. It consists of a voltage reference unit, an error amplifier, resistors for setting the output voltage, a current limit circuit, and a chip enable circuit. This IC performs with low dropout voltage and has a chip enable function to prevent destruction by over current. The R1161D301B-TR-FA has 3 modes, including a standby mode with a chip enable or standby control pin. Fast Transient Mode (FT mode) and Low Power Mode (LP mode) are alternative modes that can be realized with the ECO pin™. The consumption current is reduced to 1/10 in LP mode compared to FT mode. The output voltage is maintained between FT mode and LP mode. The output voltage of this IC is internally fixed with high accuracy. It is available in SOT-23-5 and SON-6 packages, allowing for high density mounting on boards.
