RECOMMENDED OPERATING CONDITIONS
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
PCB Layout
Ensure the VDD and GND lines are sufficiently robust. If their impedance is too high, noise pickup or unstable
operation may result. Connect a capacitor with a suitable value between the VDD and GND, and as close as
possible to the pins.
Phase Compensation
Phase Compensation of the R1514x 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 0.1 µF to 10 µF. Wiring should be made as short as possible.
Connect the capacitor, C1 between VDD pin and GND and C2 between VOUT and GND as close as possible.
Thermal Shutdown
Thermal shutdown function is included in the R1514x, if the junction temperature is more than or equal to
160°C (Typ.), the operation of regulator would stop. After that, when the junction temperature is less than or
equal to 130°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.

CE GND
When a sudden surge of electrical current travels along the VOUT pin and GND due to a short-circuit, electrical
resonance of a circuit involving an output capacitor (C2) and a short circuit inductor generates a negative voltage
and may damage the device or the load devices. Connecting a schottky diode (D1) between the VOUT pin and
GND has the effect of preventing damage to them.
