The LT3029 is a dual, micropower, low noise, low dropout linear regulator. The device operates either with a common input supply or independent input supplies for each channel, over an input voltage range of 1.8V to 20V. Each output supplies up to 500mA of output current with a typical dropout voltage of 300mV. Quiescent current is well controlled in dropout. With an external 10nF bypass capacitor, output noise is only 20?VRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 55?A quiescent current per channel makes it an ideal choice. In shutdown, quiescent current drops to less than 1?A. Shutdown control is independent for each channel, allowing for flexible power management.The LT3029 optimizes stability and transient response with low ESR ceramic output capacitors, requiring a minimum of only 3.3?F. The regulator does not require the addition of ESR, as is common with other regulators.Internal circuitry provides reverse-battery protection, reverse-current protection, current limiting with foldback and thermal shutdown. The device is available as an adjustable output voltage device with a 1.215V reference voltage. The LT3029 is offered in the thermally enhanced 16-lead MSOP and 16-lead, low profile (4mm ? 3mm ? 0.75mm) DFN packages.Applications General Purpose Linear Regulator Battery-Powered Systems Microprocessor Core/Logic Supplies Post Regulator for Switching Supplies Tracking/Sequencing Power Supplies

The ADP5034 combines two high performance buck regulators and two low dropout (LDO) regulators in a small, 24-lead 4 mm ? 4 mm LFCSP (QFN) to meet demanding performance and board space requirements.The high switching frequency of the buck regulators enables tiny multilayer external components and minimizes the board space. When the MODE pin is set high, the buck regulators operate in forced PWM mode. When the MODE pin is set low, the buck regulators operate in PWM mode when the load is around the nominal value. When the load current falls below a predefined threshold, the regulator operates in power save mode (PSM), improving the light-load efficiency.The two bucks operate out of phase to reduce the input capaci-tor requirement. The low quiescent current, low dropout voltage, and wide input voltage range of the ADP5034 LDOs extend the battery life of portable devices. The ADP5034 LDOs maintain power supply rejection greater than 60 dB for frequencies as high as 10 kHz while operating with a low headroom voltage.Regulators in the ADP5034 are activated though dedicated enable pins. The default output voltages can be externally set in the adjustable version, or factory programmable in the fixed voltage version, and can be set to a wide range of preset valuesAPPLICATIONSPower for processors, ASICS, FPGAs, and RF chipsetsPortable instrumentation and medical devicesSpace constrained devices
