LDO Regulator Platform for Small Form Factor Consumer Applications

May 27, 2015 by Jeff Shepard

Semtech Corporation today announced the SC563, a dual-output low dropout (LDO) regulator in a tiny 1.6mm x 1.2mm, 8 pin MLPD package. The SC563 LDO provides two regulated outputs for up to 300mA for each output channel. The LDO accepts an input supply rail of 2.3V to 5.5V and provides two fixed, regulated outputs, which eliminate the need for external resistor divider networks. It comes in a tiny 1.6mm x 1.2mm, ultra-thin 0.6mm 8 lead package. The LDO is ESD hardened to greater than 4kV for robust circuit protection.

“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,” said Andy Khayat, Senior Director for Consumer Power in Semtech’s Power Management Group. “That makes the SC563 perfect for portable and wearable electronics where extended battery life and tiny form factors are required.”

Key features of the SC563 include: VinN Range: 2.3V to 5.5V; Two outputs up to 300mA; Ultra-Low 180mV Dropout; Integrated output discharge; 4kV ESD Protection; and Ultra-small 1.6mm x 1.2mm x 0.60mm, 8 lead MLPD Package. Portable applications are expected to include: Wearable Electronics, Portable Video Cameras, Smart Phones, and Tablets. Non-portable applications are expected to include: Femtocells, HDTV, Set Top Box, and Networking Devices.

The SC563 is available immediately in production quantities and is priced at $0.25 each in 3,000-piece reels. The ordering code is SC563LHULTRC for 1.8V/3.3V fixed output version. Evaluation boards are also available.
