SSC SS6729

SS6729
400mA Low-dropout Linear Voltage Regulator
with Voltage Detector Function
FEATURES
DESCRIPTION
Including MOSFET for VOUT1, LDO for VOUT2,
voltage detector and shutdown control
Low dropout voltage of 550mV (typ.) at 400mA
The SS6729 is a low dropout linear regulator
with voltage detection function.
It can be divided into four main functional
output current (VOUT2)
Guaranteed 700mA output current for VOUT1
and 400mA for VOUT2
blocks, including a MOSFET for VOUT1, an LDO
for VOUT2, a voltage detector and two shutdown
controls.
Low ground current of 120µA
Output voltage accuracy of 2% for VOUT2
Current limit function
The voltage detector can be used to detect VCC.
Built-in voltage detector
The detecting voltage of the voltage detector
Shutdown control for VOUT1 and VOUT2
is from 3.0V to 4.6V in 0.1V steps, and the
output (DOUT) of the VCC voltage detection
has an adjustable delay time before indicating
APPLICATIONS
Volyage Regulator for DVD-ROM and CD-ROM
VCC. The user only needs to add one external
capacitor to implement it. When Vcc is below
Drives
Voltage Regulator for HDD and Floppy Drives
the set detection voltage, DOUT is at logic-low.
Voltage Regulator for circuits with Stepping
Motors or Servo Motors
VOUT1 is controlled by the SD1 pin. When SD1
is logic-high, the internal MOSFET for VOUT1 is
switched off, and vice versa.
