AX1006
400mA Low Dropout Linear Regulator
GENERAL DESCRIPTION
AX1006 is a low dropout positive adjustable or fixed-mode regulator with minimum of
400mA output current capability. The product is specifically designed to provide
well-regulated supply for low voltage IC applications such as high-speed bus termination and
low current 3.3V logic supply. AX1006 is also well suited for other applications such as VGA
cards. AX1006 is guaranteed to have lower than 1.2V dropout at full load current making it
ideal to provide well-regulated outputs of 1.25 to 5.0 with VOUT+1.2V to 12V input supply
VOLTAGE.
FEATURES
- 1.2V maximum dropout at full load current
- Fast transient response
- Output current limiting
- Built-in thermal shutdown
- Good noise rejection
- MLCC Capacitors are available.
- 3-Terminal Adjustable or Fixed 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5.0V
- Package: SOT-23-3L.

A resistor divider from this pin to
the VOUT pin and ground sets the
output voltage. (Ground only for
Fixed-Mode)
The output of the regulator.
(Note1,2)
The input pin of 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 dropout voltage
during the load transient
response. This pin must always
be 1.5V higher than VOUT in order
for the device to regulate
properly. (Note1)
Note1: To prevent oscillation, a 0.2uF minimum X7R or X5R dielectric is strongly recommended if ceramics are
used as output capacitors.
Note2: A minimum of 3.3uF EL capacitor to 100uF (10mΩ ≤ ESR 1Ω) must be connected from
this pin to ground to insure stability.
