SS6729

400mA Low-dropout Linear Voltage Regulator

with Voltage Detector Function

FEATURES

Including MOSFET for V

OUT1

, LDO for V

OUT2

voltage detector and shutdown control

Low dropout voltage of 550mV (typ.) at 400mA

output current (V

OUT2

)

Guaranteed 700mA output current for V

OUT1

and 400mA for V

OUT2

Low ground current of 120µA

Output voltage accuracy of 2% for V

OUT2

Current limit function

Built-in voltage detector

Shutdown control for V

OUT1

and V

OUT2

The voltage detector can be used to detect V

The detecting voltage of the voltage detector

is from 3.0V to 4.6V in 0.1V steps, and the

output (D

OUT

) of the VCC voltage detection

has an adjustable delay time before indicating

. The user only needs to add one external

capacitor to implement it. When Vcc is below

the set detection voltage, DOUT is at logic-low.

DESCRIPTION

The SS6729 is a low dropout linear regulator

with voltage detection function.

It can be divided into four main functional

blocks, including a MOSFET for V

OUT1

, an LDO

for VOUT2, a voltage detector and two shutdown

controls.

APPLICATIONS

Volyage Regulator for DVD-ROM and CD-ROM

Drives

Voltage Regulator for HDD and Floppy Drives

Voltage Regulator for circuits with Stepping

Motors or Servo Motors

OUT1

is controlled by the SD1 pin. When SD1

is logic-high, the internal MOSFET for V

OUT1

switched off, and vice versa.
