AX1110
350mA Low Dropout Linear Regulator
GENERAL DESCRIPTION
AX1110 is a low dropout positive adjustable or fixed-mode regulator with minimum of
350mA 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. AX1110 is also well suited for other applications such as
VGA cards. AX1110 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 6.4V to 12V input
supply.
FEATURES
- 1.2V maximum dropout at full load current
- Fast transient response
- Output Current Limiting
- Built-in Thermal Shutdown
- Good noise rejection
- 3-Terminal Adjustable or Fixed 1.5V, 1.8V, 2.5V, 3.3V, 5.0V
- Packages: SOT-23-3L

A resistor divider from this pin to the
Adj VOUT pin and ground sets the output

Fixed-Mode)
The input pin of regulator. Typically
a large storage capacitor (0.15Ω ≤
ESR 20Ω) is connected from this
pin to ground to insure that the input
VIN
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.
The output of the regulator. A
minimum of 10uF capacitor (0.15Ω
VOUT ESR 20Ω) must be connected
from this pin to ground to insure
stability.
