Boost type Voltage Regulator with Reset
NO. EA-092-120404
R1151N SERIES
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.

OPERATION
In these ICs, fluctuation of Output Voltage, VOUT is detected by the feed-back registers, and the result is compared
with a reference voltage with the error amplifier and control the base current of an external PNP transistor so that a
constant voltage is output. The base current is monitored with the base current limit circuit. If the base current may
be too large, the protection circuit works, further, output voltage is monitored with the built-in voltage detector. If the
set detector threshold voltage is detected, reset signal will be output.
TECHNICAL NOTES
When using these ICs, consider the following points:
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For this pur-
pose, be sure to use as much as 10µF capacitor as CL with good frequency characteristics and ESR (Equivalent Series
Resistance).
The best suitable equivalent series resistor value (ESR) is approximately 1Ω.
If the ESR of the output capacitor is too large, output may be unstable, therefore fully evaluation is necessary.
Make VDD and GND lines sufficient. When their impedance of these is high, noise pickup or unstable operation may be
the result. Connect a capacitor with a capacitance value of as much as 10µF between VDD and GND as close as possible
to these pins.
Set external components, especially output capacitor, as close as possible to the ICs.
Refer to the next equation to calculate the output delay time of C version and decide the capacitance value for the de-
lay time.
tPLH =1.83×C/(300×10-9)
C: Capacitance value (F)
Recommended pull-up resistance (R1) value is 470kΩ. If the value is too small, released voltage may shift, therefore,
use 10kΩ or more value resistor.

For Stable Operation
Phase Compensation
In these ICs, phase compensation is externally made for securing stable operation even if the load current is varied.
For this purpose, be sure to use a capacitor for the output pin with good frequency characteristics and ESR (Equivalent
Series Resistance) of which is in the range described as follows:
