BLOCK DIAGRAM
The control input pin of the regulator. This pin is connected, via a 10
resistor, to the 5V
supply to provide the base current for the pass transistor of both regulators. This allows
the regulator to have very low dropout voltage which allows one to generate a well regu-
lated 2.5V supply from the 3.3V input. A high frequency, 1
μ
F capacitor is connected
between this pin and V
IN
pin to insure stability.
The output #2 (high current) of the regulator. A minimum of 100
μ
F capacitor must be
connected from this pin to ground to insure stability.
This pin is connected to ground. It is also the Tab of the package.
The power input pin of the regulator. Typically a large storage capacitor is connected from
this pin to ground to insure that the input voltage does not sag below the minimum drop
out voltage during the load transient response. This pin must always be higher than both
V
OUT
pins by the amount of the dropout voltage (see data sheet) in order for the device to
regulate properly.
The output #1 (low current) of the regulator. A minimum of 100
μ
F capacitor must be
connected from this pin to ground to insure stability.
