ON Semiconductor, a global leader of efficient power solutions, has expanded its portfolio of low dropout (LDO) linear voltage regulators for automotive electronics modules that require very low ignition-off currents. Qualified to AEC-Q100 and operating across a wide temperature range, the new NCV86xx LDOs combine high levels of on-board functionality with typical quiescent currents (Iq) as low as 22 µA. |

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. |

SUNNYVALE, CA April 17, 2008 Maxim Integrated Products (Pink OTC Markets: MXIM) introduces the MAX8822, the industry's only white-LED (WLED) driver to combine a highly efficient negative charge pump with two independent, low-dropout (LDO) regulators. Available in a tiny, 3mm x 3mm x 0.8mm TQFN package, this single-chip solution for driving up to four WLEDs is 50% smaller than the standard two-chip solution. To achieve the industry's highest efficiency, the MAX8822 features a negative-charge-pump architecture that completely eliminates high-side in-line resistance, delaying 1x mode to 2x mode transition during battery discharge. |

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. |
