RP118x Series
100 mA Ultra-Low Supply Current Voltage Regulator
No. EA-399-181026
OVERVIEW
RP118x is a voltage regulator featuring 0.2 µA ultra-low supply current. This device is ideal for a
wearable equipment and IoT which require a long service life and a miniaturization of a battery.
KEY BENEFITS
• Achieves a low supply current (0.2 µA) and contributes to a long-life and a miniaturized battery.
• Provides a small package to achieve the smallest possible footprint solution on boards where
area is limited.
