LP2951 Datasheet

Series of Adjustable Micropower Voltage Regulators


General Description
The LP2950 and LP2951 are micropower voltage regulators with very low quiescent current (75µA typ.) and very low dropout voltage (typ. 40mV at light loads and 380mV at 100mA). They are ideally suited for use in battery-powered systems. Furthermore, the quiescent current of the LP2950/LP2951 increases only slightly in dropout, prolonging battery life.

■ 5V, 3V, and 3.3V versions available
■ High accuracy output voltage
■ Guaranteed 100mA output current
■ Extremely low quiescent current
■ Low dropout voltage
■ Extremely tight load and line regulation
■ Very low temperature coefficient
■ Use as Regulator or Reference
■ Needs minimum capacitance for stability
■ Current and Thermal Limiting
■ Stable with low-ESR output capacitors (10mΩ to 6Ω)

LP2951 versions only
■ Error flag warns of output dropout
■ Logic-controlled electronic shutdown
■ Output programmable from 1.24 to 29V
