LP2950*/2951
100mA Low-Dropout Voltage Regulator
General Description
Features
The LP2950 and LP2951 are micropower voltage
regulators with very low dropout voltage (typically 40mV at
light loads and 380mV at 100mA), and very low quiescent
current (75A typical). The quiescent current of the LP2950
/LP2951 increases only slightly in dropout, thus prolonging
battery life. This feature, among others, makes the LP2950
and LP2951 ideally suited for use in battery-powered
systems.

High accuracy 5V, guaranteed 100mA output
Extremely low quiescent current
Low-dropout voltage
Extremely tight load and line regulation
Very low temperature coefficient
Use as regulator or reference
Needs only 1μF for stability
Available in a 3-pin TO-92 package, the LP2950 is pin-
compatible with the older 5V regulators. Additional system
functions, such as programmable output voltage and logic-
controlled shutdown, are available in the 8-pin DIP and 8-
pin SOIC versions of the LP2951.
