Description

Recently, high power performance with low noise characteristics is required for every application. AKM has developed the AP1155ADL capable of supplying up to 1A of output current. It is a low-noise LDO regulator supporting a wide input voltage range while the output voltage is adjustable.
The AP1155ADL is the newest product of AP115x series, which are redesigned products of industry standards TK series that are low-noise and stable bipolar LDO regulators successfully adopted by many products.

● Low Noise

The AP1155ADL realizes high ripple rejection with low noise characteristics by adopting silicon monolithic bipolar architecture.

● Supporting High Power Applications

The AP1155ADL is capable of supplying 1A output current stably. It is housed in an HSOP-8 package with exposed-pad. Therefore, it has high heat radiation performance and is suitable for high power applications.

● Wide Range Adjustable Output Voltage

A suitable output voltage for the application can be selected in a range from 1.3V to 13.5V by external resistors.
