RICOH R1152N

R1152N SERIES
High Input Voltage Tolerant Boost Voltage Regulator
NO.EA-108-0601
OUTLINE
The R1152N Series are CMOS-based positive voltage regulator controller ICs with high output voltage
accuracy, low supply current.
The high output current regulator can be composed with this IC, an external power transistor, and capacitors.
Each of these voltage regulator controllers consists of a voltage reference unit, an error amplifier, comparators,
resistors for output voltage setting, a peak current limit protection circuit, a short current limit circuit, and a chip
enable circuit. The output voltage of these ICs is internally fixed.
In addition to low supply current by the merit of CMOS process, the chip enable function prolongs the battery
life.
Maximum operating input voltage is up to 18V, thus these ICs are very suitable for the power supply for
hand-held equipment and other power management applications using various AC adapters.
Since the package for these ICs is SOT-23-5 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.
TECHNICAL NOTES
When using these ICs, consider the following points:
Make VDD and GND lines sufficient. When their impedance is high, noise pickup or unstable operation may
result.
When you choose an external transistor, select with considering output current, input voltage, and power
dissipation. Generally, low VCE(SAT) and hFE range from 100 to 300 are the appropriate characteristics.
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, be sure to use a 10µF or more output capacitor, as close as possible to the ICs.
If you choose an electrolytic capacitor, ESR shift by temperature should be small. If you choose a ceramic
capacitor, add an appropriate series resister.
If the set output voltage is less than 4.0V, and IOUT>1A must be obtained, at least VIN≧5.0V is the appropriate
condition. (Supposed as hFE=100)
Voltage level for CE should not be floating, or middle range voltage. If the CE voltage is not appropriate, output
voltage may be unstable or conduction current may flow.
All external components should be located as close as possible to the IC, and wiring should be as short as
possible.
If hFE value of the PNP transistor is too high, output voltage may rise at low load current (less than 1mA).

2.5V
The output voltage of regulator with R1152N025x may be adjustable for any output voltage between its 2.5V
reference and VDD setting level. An external pair of resistors is required, as shown above figure.
The complete equation for the output voltage is described step by step as follows;
I2=IIC+I3 .......................................................................................................................................(1)
I3=2.5/R3 ...................................................................................................................................(2)
Thus,
I2= IIC+2.5/R3 ..............................................................................................................................(3)
Therefore,
VOUT=2.5+R2×I2 .........................................................................................................................(4)
Put Equation (3) into Equation (4), then
VOUT=2.5+R2×(IIC+2.5/R3)
=2.5×(1+R2/R3)+R2×IIC .....................................................................................................(5)
In 2nd term, or R2×IIC will produce an error in VOUT.
In Equation(5),
IIC=2.5/RIC ..................................................................................................................................(6)
R2×IIC=R2×2.5/RIC
=2.5×R2/RIC .................................................................................................................. (7)
For better accuracy, choosing R2 (<<RIC) reduces this error.
∗RIC is approximately 1.1MΩ.

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:
