AX1007
1A Low Dropout Linear Regulator
GENERAL DESCRIPTION
AX1007 is a low dropout positive adjustable or fixed-mode regulator with minimum of
1A 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. AX1007 is also well suited for other applications such as VGA cards.
AX1007 is guaranteed to have lower than 1.4V dropout at full load current making it ideal to
provide well-regulated outputs of 1.25 to 5.0 with VOUT+1.4V to 12V input supply
VOLTAGE.
FEATURES
- 1.4V 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
- Packages: SOT223, TO252 and SOT89.

Note1: See thermal regulation specifications for changes in output voltage due to heating
effects. Line and load regulation are measured at a constant junction temperature by
low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from
the package.
Note2: Line and load regulation are guaranteed up to the maximum power dissipation of 6W.
Power dissipation is determined by the difference between input and output differential
and the output current. Guaranteed maximum power dissipation will not be available
over the full input/output range.
Note3: Quiescent current is defined as the minimum output current required in maintaining
regulation. At 12V input/output differential the device is guaranteed to regulate if the
output current is greater than 10mA.
Note4: Tab is connected to the multi-layer PCB cupper area 5mm*5mm.
