R1151N

R1151N SERIES Boost type Voltage Regulator with Reset NO. EA-092-0307 OUTLINE The R1151N Series are CMOS-based boost type voltage regulator ICs with high output voltage accuracy, low supply current, and high ripple rejection. Each of these voltage regulator controllers consists of a voltage reference unit, an error amplifier, comparators, resistors for output and reset voltage setting, a current limit protection circuit, and a chip enable circuit. In addition to low consumption current by CMOS process, the chip enable function prolongs the battery life. Dynamic response and ripple rejection of the R1151N Series are excellent, further these are low noise type, plus maximum operating input voltage tolerance is up to 18.5V, thus these ICs are very suitable for the power supply for handheld equipment and other power management applications using AC adapter input voltage. The output voltage of these ICs is internally fixed with high accuracy. Since the package for these ICs is SOT-23-6 (Mini-mold) package, high density mounting of the ICs on boards is possible.
