RICOH R1510S Technical data
R1510S Series
Automatic Mode Shift 36V 300mA LDO
NO.EA-185-111026
OUTLINE
The R1510S Series are CMOS-based voltage regulator (LDO) ICs with a voltage detector (VD) that can provide 300mA of output current. Each IC is equipped with a voltage detector and a regulator that can provide the maximum 36V of operating voltage. This series has ECO function, which achieves low-power consumption and high-speed transient response by switching the ICs 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 ICs. The ICs switch 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 ICs 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).

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent damages and may degrade the lifetime 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.

All test categories were tested on the products under the pulse load condition (Tj≈Ta=25ºC) except Output Voltage Temperature Coefficient and Detector Threshold Temperature Coefficient.
1) Release output delay time is defined as the time to be taken for SENSE to change from 2V to (-VDET)+1V, and for DOUT output to become “H”.
ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent damages and may degrade the lifetime 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.

All test categories were tested on the products under the pulse load condition (Tj≈Ta=25ºC) 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 also for DOUT output to become “H”.
ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent damages and may degrade the lifetime 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.

All test categories were tested on the products under the pulse load condition (Tj≈Ta=25ºC) 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”.
ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent damages and may degrade the lifetime 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.
