austriamicrosystems Launches Ultra Low Dropout Regulator in Space Saving Wafer Level Chip Scale Package; Compact AS13985 LDO Regulator Offers an Optimal Solution for Wireless Phones and Other Battery Powered Devices.UNTERPREMSTAETTEN, Austria -- austriamicrosystems (SWX SWX Swiss Exchange (trademark of SWX Swiss Exchange) SWX SolidWorks (3D solid modeling CAD software) SWX Splitter / Wave Division Multiplexer :AMS AMS - Andrew Message System ), a leading global designer and manufacturer of analog integrated circuits Integrated circuits Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. (ICs) for communication, industrial, medical and automotive applications, today introduced an ultra low dropout regulator A low dropout or LDO regulator is a DC linear voltage regulator which has a very small input-output differential voltage. The main components are a power FET and a differential amplifier (error amplifier). (LDO LDO Low-Dropout (Used With Regulators) LDO Limited Duty Officer LDO Light Diesel Oil (petroleum) LDO Local Development Officer (Nepal) LDO Land Development Ordinance ), optimized to deliver improved operating times in battery-powered portable equipment such as PDAs, digital cameras, Bluetooth and GPS modules. The devices are designed to extend the talk and standby time of mobile cell phones as a result of its extremely low dropout (1) On magnetic media, a bit that has lost its strength due to a surface defect or recording malfunction. If the bit is in an audio or video file, it might be detected by the error correction circuitry and either corrected or not, but if not, it is often not noticed by the human voltage. The AS13985 LDO regulator is sold in a wafer level chip-scale package (WL-CSP) which means that the silicon itself is placed directly on the PCB PCB: see polychlorinated biphenyl. PCB in full polychlorinated biphenyl Any of a class of highly stable organic compounds prepared by the reaction of chlorine with biphenyl, a two-ring compound. , resulting in the smallest LDO solution. The device features extraordinarily low noise of only 30uVrms between 10Hz and 100kHz. This allows the use of a small and less expensive 1uF ceramic output capacitor. With a supply voltage rejection performance of 60dB at 1kHz and 55dB at 10kHz, the AS13985 perfectly fulfills the noise requirements for mobile phone applications. "The AS13985 solves issues that arise in the designs of state-of-the-art portable devices," said Walter Moshammer, marketing director for standard linear at austriamicrosystems. "The AS13985 offers ultra low dropout voltage, low noise and outstanding dynamic performance, as well as the extremely small size of the wafer level chip-scale package, making it ideal for battery-powered devices such as mobile phones." A digital enable pin with a turn-on time of only 150us allows system-level dynamic power management. Due to low RON characteristic, the AS13985 LDO regulator features a voltage drop Noun 1. voltage drop - a decrease in voltage along a conductor through which current is flowing free fall, drop, dip, fall - a sudden sharp decrease in some quantity; "a drop of 57 points on the Dow Jones index"; "there was a drop in pressure in the pulmonary of only 45mV at 150mA output current, going down to 0.3mV at 1mA. Furthermore, it offers over-temperature and over-current protection. With ensured 150mA output current and 500mA peak output current, the AS13985 delivers sufficient power for various applications. With an operating input voltage between 2.5V and 5.5V, the AS13985 LDO regulator is available in a variety of preprogrammed output voltages from 1.2V to 5.0V. The output voltage is regulated with an accuracy of 1%, which meets the requirements of portable battery powered products. The AS13985 device is available in a 1x1.4mm five bumps WL-CSP which is 15% of the size of a standard SOT23 package.
