NXP ultra-low dropout voltage regulator launched LD6806CX4
NXP Semiconductors NXPSemiconductorsN.V. LD6806CX4 recently announced that its ultra-low dropout regulator (LDO) is available now. The product has the characteristics of low pressure, rated at 200-mA current drop of only 60mV. LD6806CX4 ultra-small 0.76×0.76×0.47mm wafer level chip scale package (WLCSP), occupies minimal board space, design size is limited and highly demanding on the battery life of mobile devices of choice. Mobile phone battery discharge is almost linear with time, but the LDO can provide a constant regulated output voltage, which effectively improve the situation. For example, if a smart phone s battery voltage drops to 3.0V, with low dropout voltage characteristics LD6806CX4 still mandatory in stable 2.9V supply voltage applied to support SD cards. LD6806CX4 is NXP s new LD6806 series LDO in one, the major distributors is available now.
The main features of LD6806 series
? NXP s new LD6806LDO series noise is very low (only 30μVRMS), which can effectively avoid the regulated output power changes, without using any external dedicated noise reduction capacitor. ? Support for battery-powered applications, standby power consumption of only 0.1μA (typical), helps to reduce power consumption and improve battery efficiency.
? LD6806 series ESD robustness second to none, up to 10kV (HBM), combined with thermal protection and current limiting device, provides excellent circuit protection. ? LD6806 is available in two package options: the use of very small DFN1410-6 (SOT886) lead-free package LD6806F, its size is only 1.45×1.0×0.5mm; using 5-pin SOT753 general consumer packaged LD6806TD, standard size 2.9×1.5×1.0mm.
? In addition to the above package options other than NXP s low dropout voltage regulator product portfolio also includes high 75dB PSRR performance of the LDO, such as ultra-small leadless QFN package (SOT1194) of LD6805K, measuring just 1.0×1.0mm, highly of 0.55mm (max).
Key data:
? Market research firm Databeans the third quarter of 2011 in its power management tracking report (PowerManagementTracker) predicted that by 2016, global LDO regulator is expected to reach $ 3.293 billion market.
Positive comments:
? NXP semiconductor discrete devices integrated product line director of marketing DirkWittoRF, says: “Regulators in battery-powered electronic devices, power efficiency and performance management plays a crucial role. NXP believes that the high in small packages efficiency, low noise LDO and DC / DC voltage converter is required to meet a variety of essential components, especially for the rapid spread of the current smart phones, music players, tablet PCs and other portable devices. With a broad portfolio of standard products, and our economies of scale in production and quality assurance, NXP for the system designers to provide world-class energy efficiency, component integration and packaging technology, professional skills, giving them a great advantage. “
? Integrated NXP Semiconductors Discrete Division FrankHildebrandt international product marketing manager, said: “We have the latest mobile applications for LDO product leverages NXP wafer level CSP technology in the field strengths, and pressure with the current best effective combination of reduced performance, to extend battery life and reduce board space and other important aspects to create favorable conditions for a major handset OEM manufacturer for our chip-scale package mechanical properties of the LDO is given a high evaluation, which is NXP production of high recognition. “
