24LC16 手册资料 The Microchip Technology Inc. 24LC16B is a 16K bit Electrically Erasable PROM. The device is organized as eight blocks of 256 x 8 bit memory with a 2-wire serial interface. Low voltage design permits operation down to 2.5 volts with stan
LM223资料3.0 A Positive Voltage Regulators The LM323,A are monolithic integrated circuits which supply a fixed positive 5.0 V output with a load driving capability in excess of 3.0 A. These three–terminal regulators employ internal current limiting, t
The OPA357 series of high-speed, voltage-feedback CMOS operational amplifiers are designed for video and other applications requiring wide bandwidth. They are unity-gain stable and can drive large output currents. Differential gain is 0.02% and diff
Electromagnetic compatibility (EMC) - Part 3-12: Limits - Limits for harmonic currents produced by equipment connected to public low-voltage systems with input current >16 A and <=75 A per phase
The AMS1084 series of adjustable and fixed voltage regulators are designed to provide 5A output current and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed maximum 1.5V at maximum output current, d

Low Level Measurements is intended as a practical guide to making precision measurements of low level DC signals. It is useful both as a reference handbook and as an aid to understanding low level phenomena observed in the lab. Keithley’s Applicatio
In this communication, we propose a Miller compensation technique for low voltage LDO regulators which makes use of a current amplifier. The analysis shows how to design the compensation network when no voltage buffer is placed between the LDO error
The effects of eddy currents in transformer windings are considered, and a method is derived for calculating the variation of winding resistance and leakage inductance with frequency for transformers with single-layer, multilayer and sectionalised w
