To avoid turning on the external power MOSFETs too
quickly, an internal 10k resistor has been placed in series
with each of the output gate drive pins (see Functional
Block Diagram). Therefore, it only needs an external 0.1
μ
F
capacitor to create enough RC delay (10k
0.1
μ
F = 1ms)
to slow down the ramp rate of the output gate drive. In
other words, it will take a minimum of 1ms to charge up
the external MOSFET. An additional external 1k resistor
between the 0.1
μ
F capacitor and the gate of the MOSFET
(Figure 3) is required to eliminate possible MOSFET self
oscillations.

Figure 5. SMBus Controlled Low Dropout Regulator
For active-low applications in which the load needs to be
on upon power-up, an external P-channel switch can be
used (Figure 3). This load can be switched off later after the
proper protocol has been sent.
Used with the LT
1431, the LTC1623 makes a 3.3V/3A
extremely low voltage drop regulator (Figures 4 and 5). In
this application, the other output channel can be used to
drive a separate load, or it can also be used to control the
output of the LDO so that the user has total control over the
switching in and switching out of the LDO (Figure 5). Also,
with the help of the LT1304-5, the LTC1623 can be used
to make a boost switching regulator with a low standby
current of 22
μ
A (Figure 6).
