1A LOW DROPOUT POSITIVE ADJUSTABLE OR

FIXED-MODE REGULATOR

General Description

Features

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

FUNCTION

A resistor divider from this pin to the Vout pin and ground sets the output voltage.

(Ground only for Fixed-Mode)

Adj (GND)

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.

Notes: 2. 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.

3. 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.

4. 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.
