Description

Features

Typical Application Circuit

Applications

The SC900A is a highly integrated power management de-

vice for low power portable applications. The device con-

tains ﬁve adjustable low-dropout linear regulators (LDOs)

with CMOS pass-devices as well as a band-gap reference,

I2C interface, and DACs to control the output voltages.

Many features of the SC900A are programmable through

the I2C interface. These include the ability to independent-

ly turn on any combination of the ﬁve regulators. All ﬁve

of the LDO output voltages are programmable in 50mV

steps from 1.45V to 3.00V for LDOs A and B, and from

1.75V to 3.30V for LDOs C, D and E. Each LDO can have

an active shutdown or nonactive shutdown program op-

tion through the interface. There is also a reset monitor

ﬂag that is associated with LDOA. In addition, the device

has a separate programmable power good monitor ﬂag

that activates when one or more LDOs go out of regula-

tion.

The SC900A offers signiﬁcant quiescent current and

space savings to the system designer by sharing refer-

ence and biasing among ﬁve LDOs. The small and ther-

mally efﬁcient 20-lead MLPQ package make it ideal for

use in portable products where minimizing layout area is

critical.
