Anachip AP1117T25L 1a low dropout positive adjustable or fixed-mode regulator Datasheet

AP1117
1A Low Dropout Positive Adjustable or Fixed-Mode Regulator
Features
General Description
AP1117 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.
AP1117 is also well suited for other applications
such as VGA cards. AP1117 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 6.4V to 12V input supply.
- 1.4V maximum dropout at full load current
- Fast transient response
- Output current limiting
- Built-in thermal shutdown
- Packages: SOT223, TO263, TO252, TO220,
SOT89
- Good noise rejection
- 3-Terminal Adjustable or Fixed 1.5V, 1.8V, 1.9V,
2.5V, 3.3V, 5.0V
Applications
- PC peripheral
- Communication

NAME

PIN #
FUNCTION
Adj (GND)
I
1
A resistor divider from this pin to the Vout pin and ground sets the
output voltage. (Ground only for Fixed-Mode)
Vout
O
2
The output of the regulator. A minimum of 10uF capacitor (0.15Ω
≤ ESR ≤ 20Ω) must be connected from this pin to ground to insure
stability.
3
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 voltage does not sag below the minimum
dropout voltage during the load transient response. This pin must
always be 1.3V higher than Vout in order for the device to
regulate properly.

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 15W. 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.
