The AIC1729 is a low dropout linear regulator
with voltage detection function.
It can be divided into 4 main function blocks,
including MOSFET for V
OUT1
, LDO for
V
OUT2 ,
voltage detector, and two shutdown
controls.
Voltage detector can be use to detect Vcc.
The detecting voltage of the voltage detector
is from 3.0V to 4.6V with 0.1V step. And the
output (DOUT) of detecting voltage for Vcc
with delay time adjustment function to indicate
V
CC
low. User only adds one external
capacitor to finish it. When V
CC
pin is under
the set detection voltage. D
OUT
pin is logic
low.
V
OUT1
is controlled by SD1 pin. When SD1 is
logic high, the internal MOSFET for V
OUT1
will
be switched off, vice versa.
The LDO output voltage (V
OUT2
) is from 1.8V
to 4.0V with 0.1V step for different application.
It is also controlled by SD2 pin. When SD2 is
logic high, the internal LDO for V
OUT2
will be
shutdown, vice versa.
The superior characteristics of the AIC1729
include very low dropout voltage, and 2%
accuracy output voltage. Typical ground
current remains 120
μ
A, from no load to
maximum loading conditions. Dropout voltage
of V
OUT2
is 550mV at 400mA output current.
Output current limiting is provided at V
OUT1
and V
OUT2
.
AIC1729 comes in the popular SO8 package.
