GENERAL DESCRIPTION
The LP2950 and LP2951 are micropower voltage regulators ideally suited for use in battery-powered systems. These devices feature very low quiescent current (typ.75µA), and very low dropout voltage (typ.45mV at light loads and 380mV at 100mA) thus prolonging battery life. The quiescent current increases only slightly in dropout. The LP2950/LP2951 has positive transient protection up to 60V and can survive unregulated input transient up to 20V below ground.

FEATURES
• 5V, 3.3V, and 3V Versions at 100mA Output Current
• High Accuracy Output Voltage
• Extremely Low Quiescent Current
• Low Dropout Voltage
• Extremely Tight Load and Line Regulation
• Very Low Temperature Coefficient
• Current and Thermal Limiting
• Needs Minimum Capacitance (1μF) for Stability
• Unregulated DC Positive Transients 60V

ADDITIONAL FEATURES (LP2951 ONLY)
• 1.24V to 29V Programmable Output
• Error Flag Warning of Voltage Output Dropout
• Logic Controlled Electronic Shutdown

APPLICATIONS
• Battery Powered Systems
• Portable Consumer Equipment
• Cordless Telephones
• Portable (Notebook) Computers
• Portable Instrumentation
• Radio Control Systems
• Automotive Electronics
• Avionics
• Low-Power Voltage Reference
