EUP7982 Datasheet | Eutech Microelectronics

FEATURE DESCRIPTION The EUP7982 low-noise, low-dropout, linear regulator operates from a 2.5V to 5.5V input and is guaranteed to deliver 300m A. The EUP7982 is stable with small 2.2µF ceramic capacitor. Its performance suits battery powered applications because of its shutdown mode (60 n A .. typ), low quiescent current (110µA typ), and LDO voltage (140m V typ). The low dropout voltage allows for more utilization of a battery’s available energy by operating closer to its end-of-life voltage. An output fault-detection circuit indicates loss of regulation. The EUP7982 is available in MSOP package with 1.8V, 2.5v, 2.8V, 3V, 3.3V, and adjustable versions. z z z z z z z z z z z z z z z z 2.5V to 5.5V Input Range 300m A Guaranteed Output Current 60d B PSRR at 1k Hz 50µV RMS Output Voltage Noise (10Hz to 100k Hz) 140m V Dropout at 300m A Low 110µA No-Load Supply Current ≤ 1µA Shutdown Current Fast Start-up Time Stable With 2.2µF Ceramic Output Capacitors Thermal Shutdown and Short-Circuit Protection Fault Indicator Ro HS pliant and 100% Lead (Pb)-Free Wireless Handsets DSP Core Power Battery Powered Electronics Portable Information Appliances APPLICATIONS Block Diagram Figure1.
