National Semiconductor introduces seven low dropout (LDO) regulators designed to meet the power management needs of digital processor, analogue and RF subsystems. The LDOs are suitable for cell phones, notebooks, PDAs, MP3 players and other handheld portable systems. They are also for use in wireless LANs, and medical and industrial equipment. Using the LP399x family of products, designers have a portfolio of LDOs customized to meet the power needs of digital loads or RF and analogue loads in mobile and handheld devices. With their small size, low dropout voltages and low current usage during standby mode, these CMOS linear regulators enable designers to create smaller devices with longer battery life.
