LDO regulator suits small form factor consumer applications

Providing two regulated outputs for up to 300mA for each output channel, a dual output LDO regulator has been introduced by Semtech. The SC563 accepts an input supply rail of 2.3 to 5.5V and provides two fixed, regulated outputs, which eliminate the need for external resistor divider networks.

ESD hardened to greater than 4kV for robust circuit protection, the SC563 is suitable for use in portable applications, such as wearables, portable video cameras, smartphones and tablets, and non-portable applications such as femtocells, HDTVs, STBs and networking devices.

Andy Khayat, Senior Director, Consumer Power, Power Management Group, Semtech, comments: “The SC563’s ultra-small footprint, coupled with a low dropout of 180mV, enables designers to implement power supplies where small size and high efficiency are important. That makes the SC563 perfect for portable and wearable electronics where extended battery life and tiny form factors are required.”

Supplied in a tiny 1.6x1.2x0.6mm 8-lead package, the SC563 is available immediately in production quantities for $0.25 each in 3,000-piece reels. Evaluation boards are also available.
