R1151N fiche technique
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 sup-
ply 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. Dy-
namic response and ripple rejection of the R1151N Series are excellent, further these are low noise type, plus maxi-
mum operating input voltage tolerance is up to 18.5V, thus these ICs are very suitable for the power supply for hand-
held 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.
