AX1084
5A Low Dropout Linear Regulator
GENERAL DESCRIPTION
AX1084 is a low dropout positive adjustable or fixed-mode regulator with minimum of
5.0A 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. AX1084 is also well suited for other applications such as VGA cards.
AX1084 is guaranteed to have lower than 1.5V dropout at full load current making it ideal to
provide well-regulated outputs of 1.25V to 3.3V with 4.8V to 12V input supply.
FEATURES
- 1.5V maximum dropout at full load current
- Built-in thermal shutdown
- Output current limiting
- Adjustable and 1.5V/1.8V/2.5V/3.3V/5.0V fixed output voltages
- Fast transient response
- Good noise rejection
- Package: TO252-3L, TO263-2L, TO220-3L

Description
Adjustable (Ground only for fixed version)
A resistor divider from this pin to the VOUT pin and ground sets the
output voltage.
The output of the regulator. A minimum of 100uF (0.15Ω ≤ ESR
10Ω) capacitor must be connected from this pin to ground to insure
stability.
The input pin of regulator. Typically a large storage capacitor (0.15Ω
ESR 10Ω) 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 1.4V
higher than VOUT in order for the device to regulate properly.
