Low-noise LDO regulator with output voltage adjustability, supporting 1A output current
The AP1155ADL is 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 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.
● Corresponded to 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 Output Voltage can be set
A suitable output voltage for the application can be selected in a range from 1.3V to 13.5V by external resistors.
