SAN JOSE, Calif.—(BUSINESS WIRE)—December 2, 2008— Fairchild Semiconductor (NYSE: FCS) offers designers of energy-sensitive systems a 300mA low-dropout (LDO) solution balancing efficiency, transient response, and footprint size. The FAN2564 is a low V_IN LDO offering the efficiency of a switcher-based solution but in the footprint of an LDO. Traditional LDO regulators create low voltage supplies for digital processors. These LDO regulators are connected directly to the battery, resulting in poor efficiency. The FAN2564 regulator has a dropout of 100mV and operates from supplies as low as 1.8V, allowing the device to post-regulate from existing low voltage supplies in the system. By operating from a low V_IN, the voltage drop across the LDO is reduced, resulting in high efficiency linear power conversion.

This LDO consumes low quiescent current (45µA at no load) and delivers a fast transient response enabling the application to be more resilient to fluctuations in load. To accommodate the space-constrained challenges of applications with a digital load such as portable, medical, computing and computer peripherals, the FAN2564 is packaged in either compact 0.93mm x 1.41mm WL-CSP or 2mm x 2mm ultra-thin MLP packaging. In addition, the FAN2564 uses industry-standard 0402 capacitors that are quite small (1.00mm x 0.50mm), reducing board space in the overall design.

The FAN2564 is the latest addition to Fairchild’s comprehensive portfolio of LDOs, featuring low quiescent current, minimal noise and fast transient response. Integrated functions and innovative packaging allow Fairchild to deliver high-performance in the smallest footprint possible, which are important for portable applications where small size is critical.

The FAN2564 utilizes lead-free (Pb-free) terminals and has been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchild's products are designed to meet the requirements of the European Union's Directive on the restriction of the use of certain substances (RoHS).
