LP2980-N数据手册TI中文资料规格书

描述 Description

The LP2980-N is a 50-mA, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications. Using an optimized VIP (Vertically Integrated PNP) process, the LP2980-N delivers unequaled performance in all specifications critical to battery-powered designs: Dropout voltage: Typically 120 mV at 50-mA load, and 7 mV at 1-mA load. Ground pin current: Typically 375 μA at 50-mA load, and 80 μA at 1-mA load. Sleep mode: Less than 1-μA quiescent current when ON/OFF pin is pulled to less than 0.18 V. Minimum part count: Requires only a 1-μF capacitor on the regulator output. Precision output: Initial output voltage tolerance of ±0.5% (A grade). 5-V, 4.7-V, 3.3-V, 3-V, and 2.5-V versions available as standard products. For all available packages, see the orderable addendum at the end of the data sheet.
