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
CC
.
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
V
CC
. 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
V
OUT1
is controlled by the SD1 pin. When SD1
is logic-high, the internal MOSFET for V
OUT1
is
switched off, and vice versa.
