Leadis Technology Introduces Low Noise 300 mA LDO With Sequencing

Sunnyvale, CA - Leadis Technology, Inc., an analog and mixed-signal semiconductor developer of color display drivers, power management ICs, white/RGB LED drivers, audio ICs, and touch controller ICs for mobile consumer electronic devices, recently announced sample availability of the LDS8211BP, an adjustable 300 mA Low Drop Out linear regulator (LDO) with low noise characteristics, capable of regulating outputs greater than or equal to 1.175 V.

Packaged in a SOT-23-5 and stable with 1 uF MLC filter capacitors, the footprint and profile of the LDS8211BP solution is ideal for auxiliary rails where space is at a premium. This low noise LDO will not interfere with sensitive loads such as fast I/O, RF or graphics processing circuits. Furthermore, the LDS8211BP is capable of regulating low output voltages, down to 1.175 V, an increasingly common requirement with deep sub-micron CMOS loads. The heart of this LDO is a precise, self-correcting AcuRef bandgap reference, delivering an output voltage tolerance within +/-2% over the full line, load and operating temperature range. An ENABLE function permits remote power management and sequencing for complex multi-rail loads. Comprehensive protection against load short circuits, overload and excessive junction temperature yields a robust, high performance solution for low current point of load regulation in static and portable applications.

"The LDO is still the solution of choice for noise-sensitive applications below 1 A," said Paul Greenland, Senior Director of Power Management Marketing at Leadis Technology. "The LDS8211BP out-performs its CMOS counterparts in demanding applications where low noise, precision and low voltage regulation are pre-requisites for benchmark system performance."
