  • CMOS LDO Regulators for Portable Devices (.pdf)
    ROHM CMOS LDO (low drop-out) regulators are tailored for use in portable devices such as PDAs, mobile phones, digital cameras and camcorders. Lower in cost and small in packaging, ROHM CMOS LDOs offer designers a superior alternative to PWM regulators in many point-of-load regulation applications
  • Application Note - Measuring High Output Voltage Regulator Noise
    Electric-Vehicles, 48V telecom/data centers, 240W USB power delivery, and so on... these electronics applications utilize higher voltage power supplies than the 3.3V, 5V and 12V rails that we are more used to. These supplies often need to have very low output ripple and noise voltage to avoid
  • DC Performance Comparisons of CMOS vs Bipolar LDOs When Operating in "Dropout" (Vin = Nominal Vout) Mode (list devices)
    battery for their power source. Digital cameras contain high-speed memory ICs, which require tight voltage regulation at moderate loads to meet the required timing parameters of the system. Precision low dropout (LDO) regulator devices can be used to meet these requirements but in doing so, the LDO
  • How to Improve DC/DC Converter Performance with Phase Shifting Time Delay
    In most step-down power conversions where multiple output voltages are required to regulate off a single input source, the switching regulators can impose high input RMS current and noise to the POL FPGAs, DSPs and MPUs. To combat this, designers will typically implement high input filtering
  • How Can I Extend My Application's Battery Life without Sacrificing Performance?
    Decreased power consumption results in longer battery life, and, in some cases, enables the use of a smaller, less expensive battery. Traditional MCUs perform the voltage conversion with inefficient linear regulators, which waste energy and create excess heat.
  • Preventing Subsystem Brownouts in Mobile Devices
    With the ever-increasing performance of application processors and GPUs used in mobile devices, the need for a buck-boost regulator to stabilize the Li-ion battery supply-voltage terminals is becoming more and more important. This white paper examines a typical power subsystem architecture used
  • What Is A MultiVolt TM Oscillator?
    The ECS Inc. International MultiVolt TM quartz-based oscillators utilize a cutting-edge small form factor high-performance ASIC. The oscillator circuit stage uses a low-current linear voltage regulator. This significantly reduces current consumption compared to traditional oscillator designs
  • Eliminating Power Supply Design Complexity with 'Simple Digital' Modules
    voltages decreasing progressively, but still satisfy demands for tighter regulation and reduced noise performance. Learn how to meet these daunting demands while delivering maximum efficiency and peak performance with a reduced BOM cost and a minimum overall size.
  • Application Note: AAT3190 Positive/Negative Bias Supply for CCD Camera Sensors
    and output power supply ripple for the best circuit performance. CCD camera sensor applications demand several different power supply requirements: • Need to create high voltage positive and negative bias supplies from a single cell lithium-ion/polymer battery source. A single cell lithium-ion/polymer
