R1160N321B-TR-F - Brand New RICOH IC Chips
-
Description
The R1160x Series 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. These ICs perform with low dropout voltage and a chip enable function. To prevent the destruction by over current, a current limit circuit is included. The R1160x Series have 3 modes: standby mode, fast transient mode (FT mode), and low power mode (LP mode). The output voltage of these ICs is internally fixed with high accuracy. The packages for these ICs are SOT-23-5 and SON-6, allowing for high density mounting on boards.
