RP170x Series
AEC-Q100 Grade 2 Certified
300 mA 10 V Input LDO Regulator for Automotive Applications
NO. EC-205-140224
OUTLINE
The RP170x Series are LDO regulators featuring 300 mA output current that are developed with CMOS
process technology. Because of the 10 V maximum input voltage, RP170x can be used in 2 cell lithium-ion
battery powered portable appliances and besides a portable equipment. The supply current is Typ. 23 μA though
an excellent response characteristics.
The output voltage range from 1.2 V is possible. The output voltage accuracy and temperature-drift coefficient
of output voltage of the RP170x Series are excellent.
RP170x has a fold-back protection circuit and a thermal shutdown circuit. Moreover, a standby mode with ultra
low supply current can be realized with the chip enable function.
SOT-23-5 and SOT-89-5 with high power dissipation packages are available.

RECOMMENDED OPERATING RATINGS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating ratings. The semiconductor devices cannot operate normally over the recommended
operating ratings, even if when they are used over such ratings by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended operating
ratings.

TECHNICAL NOTES
When using these ICs, consider the following points:
Phase Compensation
In these ICs, phase compensation is made for securing stable operation even if the load current is varied. For
this purpose, use a capacitor C2 with 1.0 μF or more and good ESR (Equivalent Series Resistance).
(Note: If additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for
phase compensation, the operation might be unstable. Because of this, test these ICs with as same external
components as ones to be used on the PCB.)
PCB Layout
Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result.
Connect a capacitor C1 with a capacitance value as much as 1.0 μF or more between VDD and GND, and as
close as possible to the pins.
Set external components, especially the output capacitor C2, as close as possible to the ICs, and make wiring
as short as possible.

C1

D1
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.

ESR vs. Output Current
Ceramic type output capacitor is recommended for this series; however, the other output capacitors with low
ESR also can be used. The relations between IOUT (Output Current) and ESR of an output capacitor are shown
below. The conditions when the white noise level is under 40 μV (Avg.) are marked as the hatched area in the
graph.
