LND48XX

• 400mA output within 2% over temperature
• Very low quiescent current
• Low dropout voltage (420mV 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 SGS-Thomson- L48XX Series, but has lower ground current, higher accuracy of output voltage and extremely tight load and line regulation. The 5 pin version (adjust model) and 4 pin version (fixed model) have a shutdown input.

This LND48XX series of fixed-voltage 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 LND48XX series of fixed-voltage regulators features very low quiescent current(100mA Typ.) and very low drop output voltage (Typ. 60mV at light load and 420mV at 400mA). This 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 regulators is offered in 3-pin TO- 220 package compatible with other fixed voltage regulators. Adjust model is offered in 5-pin TO- 220 package and fixed model with shutdown input is offered in 4-pin TO-220 package.
