regulator

Texas Instruments Incorporated introduced a 4.5-V to 52-V wide-input voltage boost controller, intended for industrial and battery-powered applications where the output is a regulated current instead of a regulated voltage. In addition, TI launched two integrated low-dropout (LDO) regulators with internal protection circuits that simplify power design for industrial systems.

Linear Technology Corporation introduces the LTM8021, a complete DC/DC uModule regulator point-of-load (POL) system with on-board inductor and power components in a package that resembles a surface-mount IC. The LTM8021 operates from input supplies from 3V to 36V (40Vmax) and delivers up to 500mA. The LTM8021's tiny footprint (6.25mm x 11.25mm), low profile (2.8mm) and light weight (0.49g), enable system designers to solder the device on the backside of the circuit board, creating room on top for digital ICs such as FPGAs, memory and passives including HDMI, Ethernet or SMA connectors.

SUNNYVALE, CA February 21, 2008 Maxim Integrated Products (Pink Sheets: MXIM) introduces the MAX13410E - MAX13415E* half-duplex, RS-485/RS-422 transceivers with an integrated low-dropout (LDO) regulator. These transceivers utilize Maxim's proprietary AutoDirection control architecture to automatically enable the driver when transmitting data. AutoDirection control thus eliminates the need for a driver-enable control signal, as well as the optocouplers typically required for control-line isolation. To further save space and reduce cost, the integrated LDO regulator features a wide, 6V to 28V supply range, eliminating the need to regulate isolated power supplies. The MAX13410E%u2013MAX13415E are ideal for isolated-metering, automotive, and industrial applications.
