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.

TECHNICAL NOTES
When using these ICs, consider the following points:
Phase Compensation
Phase Compensation of the R1514x Series has been made internally for stable operation even though the
load current would vary. Therefore, without the capacitors, C1 and C2, the output voltage is regulated, however,
for more stable operation, use capacitors as C1 and C2. Especially, if the input line is long and impedance is high,
C1 is necessary. Moreover, if you use rather large C2, transient response will be improved. Recommended value
is in the range from 0.1μF to 10μF. Wiring should be made as short as possible.
Connect the capacitor, C1 between VDD pin and GND pin and C2 between VOUT and GND as close as possible.
GND wiring of mounting on board
No.2 pin and No.4 pin of SOT-89-5 package must be wired to the GND plane. No.2 pin, No.4 pin and No.5 pin
of HSOP-6J package must be wired to the GND plane when it is mounted on board.
Thermal Shutdown
Thermal shutdown function is included in the R1514x Series, if the junction temperature is equal or more than
+150°C(Typ.), the operation of regulator would stop. After that, when the junction temperature is equal or less
than +125°C(Typ.), the operation of regulator would restart. Unless the cause of rising temperature would
remove, the regulator repeats on and off, and output waveform would be like consecutive pulses.
Chip Enable Circuit
Do not make voltage level of chip enable pin keep floating level, or in between VCEH and VCEL. Otherwise, the
output voltage would be unstable or indefinite, or unexpected current would flow internally.
