The S-818 Series is a positive voltage regulator developed by CMOS technology and featured by low dropout
voltage, high output voltage accuracy and low current consumption.
Built-in low on-resistance transistor provides low dropout voltage and large output current. A ceramic capacitor
of 2 μF or more can be used as an output capacitor. A shutdown circuit ensures long battery life.
The SOT-23-5 miniaturized package and the SOT-89-5 package are recommended for configuring portable
devices and large output current applications, respectively.
Features
• Low current consumption: At operation mode: Typ. 30 μA, Max. 40 μA
At shutdown mode: Typ. 100 nA, Max. 500 nA
• Output voltage: 2.0 to 6.0 V, selectable in 0.1 V steps.
