R1510S Series
Automatic Mode Shift 36 V 300 mA LDO
OUTLINE
NO.EA-185-140724
The R1510S is a voltage regulator (LDO) IC with a voltage detector (VD) featuring 300mA output current that
is developed with CMOS process technology. Each IC is equipped with a voltage detector and a regulator that
can provide the maximum 36V of operating voltage. This device has ECO function, which achieves low-power
consumption and high-speed transient response by switching the IC to low-power consumption mode at light load
condition and switching to high-speed mode at heavy load condition.
The switching point is internally fixed inside the IC. The IC switches from low-power consumption mode to high-
speed mode when IOUT=12mA (Typ.), and switch from high-speed mode to low-power consumption mode when
IOUT=3mA (Typ.).
Each IC is composed of a reference voltage unit, an error amplifier, a resistor network for setting output voltage,
an output current limit circuit for preventing overcurrent destruction, and a thermal shutdown circuit. The output
voltage and the detector threshold are internally fixed inside the IC.
The output voltage accuracy is ±1.6% and the detector threshold accuracy is ±1.7%. The output voltage type
is Nch open drain. The versions for the IC are selectable from A version (CE, VIN Detector), B version (SENSE
Detector), C version (Release Delay Circuit, VIN Detector), and D version (Release Delay Circuit, VOUT Detector).

All test items listed under Electrical Characteristics are done under the pulse load condition (Tj≈Ta=25°C) except
Output Voltage Temperature Coefficient and Detector Threshold Temperature Coefficient.
∗1) Minimum operating voltage is defined as the power supply voltage of which output voltage becomes lower
than 0.1V at the detection.
∗2) Release output delay time is defined as the time to be taken for VIN to change from 2V to (-VDET) +1V, and
for DOUT output to become “H”.
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.

All test items listed under Electrical Characteristics are done under the pulse load condition (Tj≈Ta=25°C) except
Output Voltage Temperature Coefficient and Detector Threshold Temperature Coefficient.
∗1) Minimum operating voltage is defined as the power supply voltage of which output voltage becomes lower
than 0.1V at the detection.
∗2) Release output delay time is defined as the time to be taken for VOUT to change from 2V to (-VDET) +1V, and
also for DOUT output to become “H”.
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.

TECHNICAL NOTES
Phase Compensation
This IC is using the capacitance of output capacitor (COUT) and the ESR as phase compensation for the stable
operation of the IC even if the output load varies. Therefore, please make sure to use a capacitor (COUT) with
6.8µF or more.
If the ESR value is large, the output may result in unstable, therefore, please make full evaluation on the
temperature characteristics and the frequency characteristics.
PCB Layout and GND Wiring
The high impedances of VDD and GND could be a reason for the noise pickup and unstable operation. Therefore,
make the impedances of VDD and GND as low as possible. A capacitor (CIN) with 0.1µF or more has to be
connected between VDD pin and GND pin, and the wirings between them have to be short as possible. The
capacitor (COUT) for phase compensation has to be connected between VOUT pin and GND pin, and the wirings
between them have to be short as possible.

R1510S

OPERATION MANUAL
Voltage Regulator (VR)
Voltage Regulator (VR) operates within the input voltage range of 3.5V to 36V. The output voltage is adjustable
within the range of 2.5V to 12V by 0.1V step. By changing the current value of the control circuit according to the
load current, the supply current at the light load condition can be minimized and also be able to achieve high
speed response. When the load current becomes 12mA (Typ.) or more, the control circuit switches to high-speed
mode and when the load current becomes 3mA or lower, it switches to low-power consumption mode. Hysteresis
is set for the output current between 3mA to 12mA (Typ.).
These current values are internally fixed inside the IC. When the mode switching is caused by the load current
change, the output voltage will be changed as the graph below shows. The load current dependencies (Load
Regulation) of output voltage in Electrical Characteristics have been tested at the following points: 0.1mA, 7mA
(Low-power consumption mode), 20mA, and 300mA.

Output Current IOUT (mA)
During the period of 100µsec immediately after High-speed mode is switched to Low-power consumption mode,
the current value (IOUTH), which switches Low-power consumption mode back to High-speed mode, is increased
3 times. Therefore, during this time period, the IC can still operate with Low-power consumption mode even if the
load current is between 12mA to 36mA (Typ.).
R1510SxxxA can turn on and off the operation of VR by CE pin.
Voltage Detector (VD)
Voltage Detector (VD) operates within the input voltage range of 1.8V to 36V (R1510SxxxA/C/D) and 3.0V to
36V (R1510SxxxB). The detector threshold is adjustable in the range of 2.3V to 12V by 0.1V step. If the monitor
voltage is lower than the detector threshold, DOUT outputs “L”. In the case of R1510SxxA/B, if the monitor voltage
becomes more than the released voltage, DOUT outputs “H”. In the case of R1510SxxxC/D, if the monitor voltage
becomes more than the released voltage, the capacitor of the release output delay time pin (CD) starts to get
charged. DOUT output maintains “L” until CD reaches to the threshold value. Once CD value becomes more than
the threshold value, DOUT outputs “H”. In the case of R1510SxxxC/D, if the monitor voltage becomes lower than
the detector threshold, the capacitor of CD starts to get discharged. Therefore, if the monitor voltage becomes
more than the released voltage without electrical discharge, the release output delay time afterwards becomes
less than the existing release output delay time (tDELAY).

If VIN voltage is raised suddenly from the less than the minimum operating voltage to the less than the release
voltage, VIN voltage momentarily passes through the unstable range (from 0V to the minimum operating voltage),
therefore, DOUT may output “H” (unstable) once then output “L” afterwards. Similarly, if VIN voltage is raised from
the less than the minimum operating voltage to the more than the release voltage, VIN momentarily passes through
the unstable range (from 0V to the minimum operating voltage), therefore, DOUT may output “H” once.
17
R1510S
NO.EA-185-140724
Release Output Delay Time
The release output delay time (Power-on Reset Time (tDELAY)) of R1510SxxxC/D can be set by the capacitor of
CD pin. The relationship between the capacitor capacitance and tDELAY is as shown in the following equation.
tDELAY(s)=7.0×105×CD(F)
The upper limit of the capacitance value for the CD pin capacitor is 1µF. The capacitor operates normally with
more than 1µF; however, if the setting time (tDELAY) is set longer, the setting time differences could become bigger.
Also, if the detect output delay time becomes longer; the response of the VD output pin will be slow to make a
momentary stop.
If the VDD pin voltage is decreased with more than the through rate as it is shown in the graph below, the IC
does not operate normally. If there’s any possibility of this, please minimize the voltage fluctuation of VDD pin by
using CIN.

Thermal Shutdown
If the junction temperature (Tj) becomes more than 140°C(Typ.) due to the heat generation in the voltage
regulator, the output driver will be turned off to protect the IC and the voltage regulator output will be turned off. If
the junction temperature becomes less than 125°C(Typ.), the output driver will be turned on and the voltage
regulator output will be turned on. Unless the cause of the heat generation is not removed, the voltage regulator
repeats turns on and off, so the output voltage will be a pulsing form.
R1510SxxxD Voltage Setting
The voltage detector (VD) of R1510SxxxD detects the output voltage drop of the voltage regulator (VR). If the
VD release voltage is set to more than the VR output voltage, the VD will not be canceled even if the VR output
voltage returns to the normal value after VD detected the output voltage drop of VR. To avoid this, there have to
be voltage differences between the voltage regulator’s output voltage (VOUT) and the voltage detector’s release
voltage (+VDET). Also, the following conditions have to be met.
(VR Output Setting Voltage) x 0.964 > (VD Detect Setting Voltage) x1.03 x 1.075
In case of using the products with the VR output voltage and the VD detector threshold that is not met the above
conditions, please make sure to give greater consideration on the system operation before use.
