R1130x SERIES
300mA LDO REGULATOR
NO.EA-078-140822
OUTLINE
The R1130x Series are CMOS-based voltage regulator (VR) ICs. VR function has features of high ripple
rejection, low dropout voltage, high output voltage accuracy, and ultra-low supply current. Each of these ICs
consists of a voltage reference unit, an error amplifier, resistors for setting output voltage, and a current limit
circuit. Each of the R1130xxxxA/B type includes also a chip enable circuit.
The output voltage of the R1130xxxxC type is adjustable with external resistors.
The output voltage of R1130xxxxA/B is fixed in the IC. Low supply current by the merit of CMOS process and
built-in transistors with low ON-resistance make low dropout voltage. These regulators in the R1130x Series are
remarkable improvement on the current regulators in terms of ripple rejection, input transient response, and load
transient response. Maximum Output Current is large for its compact size.
Thus, the R1130x Series are suitable for power supply for CD-drives, DVD-drives, and so forth.
Since the packages for these ICs are the SOT-89-5 package or HSON-6 (Discontinued), high density mounting
of the ICs on boards is possible.

∗) Tab and tab suspension leads are VDD level. (They are connected to the reverse side of the IC.)
The tab is better to be connected to the VDD, but leaving it open is also acceptable.
The tab suspension leads should be open and do not connect to other wires or land patterns.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the
permanent damages and may degrade the life time and safety for both device and system using the device
in the field.
The functional operation at or over these absolute maximum ratings is not assured.
RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the
recommended operating conditions, even if when they are used over such conditions by momentary
electronic noise or surge. And the semiconductor devices may receive serious damage when they continue
to operate over the recommended operating conditions.

APPENDIX
* Technical Notes on Output Voltage Setting of C type
Figure 1. Adjustable Regulator (C type)
The Output Voltage of Regulator in R1130xxxxC may be adjustable for any output voltage between its 1.8V
reference and its VDD setting level. An external pair of resistors is required, as shown in Figure 1.
The complete equation for the output voltage is described step by step as follows;
I2=IIC+I3 ································································································· (1)
I3=1.8/R3 ······························································································· (2)
Thus,
I2=IIC+1.8/R3
··························································································· (3)
Therefore,
VOUT=1.8+R2×I2 ·····················································································
Put Equation (3) into Equation (4), then
VOUT=1.8+R2×(IIC+1.8/R3)
=1.8×(1+R2/R3)+R2×IIC ····································································
In 2nd term, or R2×IIC will produce an error in VOUT.
In Equation (5),
IIC=1.8/RIC ·······························································································
R2×IIC=R2×1.8/RIC
=1.8×R2/RIC ··················································································
For better accuracy, choosing R2 (
