AP1115

0.6A Low Dropout Positive Adjustable or Fixed-Mode Regulator

Features

General Description

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.

• 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

FUNCTION

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

(Ground only for Fixed-Mode)

(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.

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 5W. Power dissipation is determined by the

input/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 to maintain regulation. At 12V input/output differential the

device is guaranteed to regulate if the output current is greater than 10mA.
