» Product Change Notification
The NCP706 is a Very Low Dropout Linear Regulator with capability to drive up to 1 A of load current while maintaining a superior output accuracy of 1%. The output accuracy is rated for all temperature, load and line variations. The operating input voltage ranges from 2.4V to 5.5V making this devices suitable for Li-ion battery powered products as well as post-regulation applications. The product is available in fixed output voltage options or can be configured as adjustable. The NCP706 is fully protected against overheating and output short circuit to ensure the safety of the LDO and its applications. Short circuit protection options include "auto restart" and "latch off" (NCP706B or NCP706AB). Output Active-Discharge options are also available (NCP706A or NCP706AB). Very small 8-pin xDFN8 1.2 x 1.6mm, 0.4mm pitch package makes this device suitable for space constrained portable applications such as tablets and smartphones. Please contact your sales office for additional output voltage options.
