AP1115
0.6A Low Dropout Positive Adjustable or Fixed-Mode Regulator
Features
General Description
• 1.3V maximum dropout at full load current
• Fast transient response
• Output current limiting
• Built-in thermal shutdown
• Packages: SOT89, TO92
• Good noise rejection
• 3-Terminal Adjustable or Fixed 1.5V / 1.8V / 2.5V
/ 2.8V / 3.0V / 3.3V / 3.5V / 5.0V
Applications
• PC peripheral
• Communication
AP1115 is a low dropout positive adjustable or
fixed-mode regulator with minimum of 0.6A 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.
AP1115 is also well suited for other applications
such as VGA cards. AP1115 is guaranteed to have
<1.3V dropout at full load current making it ideal to
provide well regulated outputs of 1.25V to 5V with
up to 18V input supply.

FUNCTION
I
A resistor divider from this pin to the Vout pin and ground sets the output voltage.
(Ground only for Fixed-Mode)
O
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.
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
I 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.
