New LDO for small form factor consumer applications such as wearables

04-06-2015 | Semtech | Power

A new dual-output low dropout (LDO) regulator in a tiny 1.6mm x 1.2mm, 8-pin
MLPD package, the SC563 has been introduced by Semtech. The SC563 LDO
provides two regulated outputs for up to 300mA for each output channel. It
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. The LDO is ESD hardened to greater than 4kV for robust circuit
protection, says the company.

“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, Semtech Power Management Group. “That makes the SC563 perfect for
portable and wearable electronics where extended battery life and tiny form
factors are required.”

Typical portable applications include wearable electronics, video cameras,
smart phones and tablets. Non-portable applications include femtocells,
HDTVs, set-top boxes and networking devices.
