LOW DROPOUT CMOS VOLTAGE REGULATOR
Rev.3.1_00
The S-814 Series is a low dropout voltage, high output voltage accuracy and low current consumption positive
voltage regulator developed utilizing CMOS technology.
Built-in low ON-resistance transistors provide low dropout voltage and large output current. The ON/OFF circuit
ensures long battery life.
Various types of output capacitors can be used in the S-814 Series compared with the past CMOS voltage
regulators. (i.e., Small ceramic capacitors can also be used in the S-814 Series.)
The SOT-23-5 miniaturized package and the SOT-89-5 packages are recommended to use for configuring
portable devices and large output current applications, respectively.
 Features
• Output voltage:
2.0 V to 6.0 V, selectable in 0.1 V step
• Output voltage accuracy: ±2.0%
• Dropout voltage:
170 mV typ. (5.0 V output product, IOUT=60 mA)
• Current consumption:
During operation: 30 μA typ., 40 μA max.
During power-off: 100 nA typ., 500 nA max.
• Output current:
Possible to output 110 mA (3.0 V output product, VIN=4 V)*1
Possible to output 180 mA (5.0 V output product, VIN=6 V)*1
• Output capacitor:
A ceramic capacitor of 0.47 μF or more can be used.
• Built-in ON/OFF circuit:
Ensures long battery life.
• Built-in short-circuit protection circuit
• Operation temperature range: Ta=−40°C to +85°C
• Lead-free, Sn 100%, halogen-free*2
*1. Attention should be paid to the power dissipation of the package when the output current is large.
*2. Refer to “ Product Name Structure” for details.
 Applications
