SC560中文资料Dual Output Low Noise LDO Linear Regulator数据手册Semtech规格书

描述 Description

The SC560 is a family of dual output, ultra-low dropout linear voltage regulators designed for use in battery powered wireless applications. The SC560A, SC560B, and SC560C provide adjustable output voltages that can be set using two external resistors.
