The LTC3408 is a high efficiency monolithic synchronous buck regulator optimized for WCDMA power amplifier applications. The output voltage can be dynamically programmed from 0.3V to 3.5V. At VOUT > 3.6V an internal 0.08? bypass P-channel MOSFET connects VOUT directly to VIN, eliminating power loss through the inductor.The input voltage range is 2.5V to 5V making the LTC3408 ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems.Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode.The LTC3408 is available in a low profile (0.75mm) 8-lead 3mm ? 3mm DFN package.Applications WCDMA Cell Phone Power Amplifiers Wireless Modems

The LT3020 is a very low dropout voltage (VLDO?) linear regulator that operates from input supplies down to 0.9V. This device supplies 100mA of output current with a typical dropout voltage of 150mV. The LT3020 is ideal for low input voltage to low output voltage applications, providing comparable electrical efficiency to that of a switching regulator.The LT3020 regulator optimizes stability and transient response with low ESR, ceramic output capacitors as small as 2.2?F. Other LT3020 features include 0% typical line regulation and 0.2% typical load regulation. In shutdown, quiescent current drops to 3?A.Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting with hysteresis, and reverse-current protection. The LT3020 is available as an adjustable output device with an output range down to the 200mV reference. Three fixed output voltages, 1.2V, 1.5V and 1.8V, are also available.The LT3020 regulator is available in the low profile (0.75mm) 8-lead (3mm ? 3mm) DFN package with exposed pad and the 8-lead MSOP package.Applications Low Current Regulators Battery-Powered Systems Cellular Phones Pagers Wireless Modems

The LTC3407-2 is a dual, constant frequency, synchronous step down DC/DC converter. Intended for low power applications, it operates from 2.5V to 5.5V input voltage range and has a constant 2.25MHz switching frequency, allowing the use of tiny, low cost capacitors and inductors with a profile ?1.2mm. Each output voltage is adjustable from 0.6V to 5V. Internal synchronous 0.35?, 1.2A power switches provide high efficiency without the need for external Schottky diodes.A user selectable mode input is provided to allow the user to trade-off noise ripple for low power efficiency. Burst Mode? operation provides high efficiency at light loads, while Pulse Skip Mode provides low noise ripple at light loads.To further maximize battery life, the P-channel MOSFETs are turned on continuously in dropout (100% duty cycle), and both channels draw a total quiescent current of only 40?A. In shutdown, the device draws <1?A.
