Products & Services > Intellectual Property >Programmable LDO

Our modular LDO technology offers a low dropout linear regulator which supports multiple drive capabilities from 5 mA to more than 100 mA. Our modular design is based on building the LDO out of units rather than hand-crafting for multiple drives. Each unit supplies output current  from  5mA  to  10mA  with output  voltage  of 1.2V  and a typical quiescent current  0f 200µA  including our ultra low noise reference. The design is available in 90nm CMOS technology. The LDO design offers a bypass mode which allows the input voltage to pass directly to the output. A fast start-up mode allow typical start-up time of less than 40µs, very low noise where typical noise at 1MHz equal 40.nV/ÖHz, Excellent transient response and load and line regulation are key characteristics of this IP. A Bandgap reference is used in this IP to achieve a worst case accuracy of ±2.5% over volt, process, temperature, and load variations. The total area of one unit LDO including the bandgap reference is equal 0.165mm X 0.316mm.
