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
