LOW DROPOUT CMOS VOLTAGE REGULATOR

S-818 Series

Seiko Instruments Inc.

1

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.

• High accuracy output voltage: ±2.0%

• Peak output current:

*1

*1

• Low dropout voltage:

• A ceramic capacitor (2 µF or more) can be used as an output capacitor.

• Built-in shutdown circuit

• Small package:

SOT-23-5, SOT-89-5

• Lead-free products

*1. Attention should be paid to the power dissipation of the package when the output current is large.

Applications

• Power source for battery-powered devices, personal communication devices and home electric/electronic

appliances
