R1170D291B-TR-F - Brand New RICOH IC Chips
-
Description
The R1170D291B-TR-F is a positive voltage regulator IC by CMOS process. It is part of the R1170 Series, known for their high ripple rejection, low dropout voltage, high output voltage accuracy, and low consumption current. The IC includes 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 a thermal-shunt circuit. The output voltage of the R1170 is fixed in the IC. With low consumption current and low dropout voltage, this IC helps prolong battery life. It offers remarkable improvements in terms of ripple rejection, input transient response, and load transient response. Despite its compact size, it can handle a large maximum output current, making it suitable for various power sources for portable appliances. It comes in SOT-89-5 and HSON6 packages, allowing for high density mounting on boards.
