low dropout 中文意思是什麼
low dropout
解釋
低壓差-
A white led driver circuit is presented in this paper. the circuit drives up to four white leds with regulated constant current for uniform intensity. by utilizing proprietary adaptive 1x / 1. 5x modes and ultra - low - dropout current regulators, it maintains the highest possible efficiency over the full 1 - cell li + battery input voltage range
整體電路以恆定電流驅動4隻白光led ,利用1倍/ 1 . 5倍分數型電荷泵和低壓差電流調節器,在整個鋰電池供電電壓范圍內保持最高的效率,並使四個白光led獲得均勻的亮度。 -
The 1mhz fixed frequency switching allows for tiny external components and the regulation scheme is optimized to ensure low emi and low input ripple. an external resistor sets the full - scale led current, while two digital inputs control on / off and select amongst three levels of brightness. the circuit operates in 1x mode until just above dropout
工作在1mhz固定頻率,採用線性調制模式使輸入紋波大大減小;利用一個外部電阻可以設置滿量程led電流;外接兩個數字信號控制晶元開關並選擇led三級亮度中的一級;具有過溫、過壓/欠壓等保護功能,工作溫度范圍為- 40 + 85 。 -
Regulator ground current increases only slightly in dropout, further prolonging the battery life. the rt9016 also works with low - esr ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand - held wireless devices. the rt9016 consumes less than 0. 01a in shutdown mode and has fast turn - on time less than 50s

Design of cmos low - dropout voltage integrated regulator
低壓差集成穩壓器的設計 -
And it notes that studies have shown that large schools are linked to low student performance and higher dropout rates
另外研究還表明大規模的高中往往與學生成績差和相對較高的輟學率掛鉤。 -
Unlike the traditional single mode of charge pump structure, the paper adopted 1x / 1. 5x fractional adaptive charge pump, which can automatically convert working mode with the change of input voltage, and utilized ultra - low - dropout current regulators to make 0. 15v led _ minimum regulation voltage in order to remain the charge pump working mostly in higher - efficiency 1x mode
與傳統的單一轉換模式的電荷泵結構不同,本文採用了1倍/ 1 . 5倍分數型自適應電荷泵技術,可隨輸入電壓的變化自行轉換工作模式;採用低壓差電流調節器使led陰極最小調節電壓僅為0 . 15v ,使電荷泵更多地工作在效率更高的1倍模式。
