LOW DROPOUT CMOS VOLTAGE REGULATOR
S-818 Series
Note : Please consider power dissipation of the package when the output current is large.
Package
y
5-pin SOT-23-5 (Package drawing code: MP005-A)
y
5-pin SOT-89-5 (Package drawing code: UP005-A)
The S-818 Series is a positive voltage regulator developed
utilizing CMOS technology 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
μ
F
or more can be used as an output capacitor. A power-OFF
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.
