Understanding Linear Regulators and their Key Performance Parameters


Low-dropout regulators, commonly known as LDOs, are used extensively in a wide variety of electronic applications across many different industries. An LDO is generally perceived as a simple and inexpensive way to regulate and control an output voltage that is delivered from a higher input voltage supply. However, cost and simplicity are not the only reason for their widespread use. In fact, tod... » read more

Test Challenges Rising For Mobile Devices


Smartphone and tablets continue to advance at a dizzying pace. On the component side alone, the latest mobile devices are moving towards 64-bit application processors, multi-mode RF front-ends, higher-end cameras and flashy LCD screens. Some systems even boast fingerprint scanners and heart rate sensors. But an obvious part of the system continues to lag behind the curve—battery life. In r... » read more
