Linear Technology Corp. (Milpitas, CA) announced its new LTC3405A high-efficiency, monolithic buck regulator in a ThinSOT package, which can supply 300mA of continuous output current to output voltages as low as 0.8V that are commonly used in hand-held applications. The LTC3405A is stable with a low ESR ceramic output capacitor, which eliminates the need for a more expensive and larger tantalum capacitor.
The LTC3405A can deliver up to 300mA of output current from an input-voltage range of 2.5V to 5.5V, making it suitable for single-cell, lithium-ion, battery-powered applications. The 1.5MHz switching frequency allows the use of tiny, surface-mount components and keeps the switching noise well above the pass-band of most communication systems. The small implementation footprint makes the LTC3405A suitable for space-constrained environments such as cellular phones, PDAs, wireless and DSL modems, and digital cameras.
The LTC3405A is available from stock in a six-lead ThinSOT package. Pricing starts at $1.61 for the LTC3405A in 1,000-piece quantities.
