Low Dropout Regulator Platform for Small Form Factor Consumer Applications

Semtech Corp. 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. The LDO is ESD hardened to greater than 4kV for robust circuit protection.

Key Features of SC563:

  • VIN Range: 2.3V to 5.5V
  • Two outputs up to 300mA
  • Ultra-Low 180mV Dropout
  • Integrated output discharge
  • 4kV ESD Protection
  • Ultra-small 1.6mm x 1.2mm x 0.60mm, 8 lead MLPD Package

Portable Applications:  wearable electronics, portable video cameras, smart phones, tablets

Non-Portable Applications:  femtocells, HDTV, set top box, 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.
