1 / 5 page LND2931 100mA Low Dropout Voltage Regulator DATA SHEET GENERAL DESCRIPTION • 3- terminal regulators ( To-220-5, SO-8 for LND2931) • 100mA output within 2% over temperature • Very low quiescent current • Low dropout voltage (300mV Typ) • Extremely tight load and line regulation • Very low temperature coefficient • Current and thermal limiting • Unregulated DC input can withstand –20V reverse battery and +60V positive transients • Direct replacement for National LM2931 fixed series, but has lower ground current, higher accuracy of output voltage and extremely tight load and line regulation. For adjust model LND2931 see typical applications on figure 2. FEATURES This series of fixed-voltage and adjustable monolithic micropower voltage regulators is designed for a wide range of applications. This device is an excellent choice for use in battery- powered application. Furthermore, the quiescent current increases only slightly at dropout, which prolongs battery life. This series of fixed-voltage ( Typ. 60mV at light load and 300mV at 100mV) includes a tight initial tolerance of 0.5% typ., extremely good load and line regulation of 0.05% typ., and very low output temperature coefficient. This series of fixed- voltage and adjustable regulators is offered in 3- pin TO-92 package (TO-220-5, SO-8 for LND2931) compatible with other fixed-voltage regulators. APPLICATIONS • High-efficiency linear regulators • Battery powered systems • Portable/Palm top/ Notebook Computers • Portable consumer equipment • Portable instrumentation • Automotive Electronics • SMPS Post Regulator • Linear Dimensions, Inc. • 445 East Ohio Street, Chicago IL 60611 USA • tel 312.321.1810 • fax 312.321.1830 • www.lineardimensions.com • PIN CONFIGURATION 1 2 3 45 6 7 8 Output Shutdown GND Feedback Input LND2931 GND GND GND |
