1 / 22 page Semiconductor Components Industries, LLC, 2013 April, 2013 − Rev. 26 1 Publication Order Number: LP2950/D LP2950, LP2951, NCV2951 100 mA, Low Power Low Dropout Voltage Regulator The LP2950 and LP2951 are micropower voltage regulators that are specifically designed to maintain proper regulation with an extremely low input−to−output voltage differential. These devices feature a very low quiescent bias current of 75 mA and are capable of supplying output currents in excess of 100 mA. Internal current and thermal limiting protection is provided. The LP2951 has three additional features. The first is the Error Output that can be used to signal external circuitry of an out of regulation condition, or as a microprocessor power−on reset. The second feature allows the output voltage to be preset to 5.0 V, 3.3 V or 3.0 V output (depending on the version) or programmed from 1.25 V to 29 V. It consists of a pinned out resistor divider along with direct access to the Error Amplifier feedback input. The third feature is a Shutdown input that allows a logic level signal to turn−off or turn−on the regulator output. Due to the low input−to−output voltage differential and bias current specifications, these devices are ideally suited for battery powered computer, consumer, and industrial equipment where an extension of useful battery life is desirable. The LP2950 is available in the three pin case 29 and DPAK packages, and the LP2951 is available in the eight pin dual−in−line, SOIC−8 and Micro8 surface mount packages. The ‘A’ suffix devices feature an initial output voltage tolerance 0.5%. Features Low Quiescent Bias Current of 75 mA Low Input−to−Output Voltage Differential of 50 mV at 100 mA and 380 mV at 100 mA 5.0 V, 3.3 V or 3.0 V 0.5% Allows Use as a Regulator or Reference Extremely Tight Line and Load Regulation Requires Only a 1.0 mF Output Capacitor for Stability Internal Current and Thermal Limiting NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These Devices are Pb−Free and RoHS Compliant LP2951 Additional Features Error Output Signals an Out of Regulation Condition Output Programmable from 1.25 V to 29 V Logic Level Shutdown Input (See Following Page for Device Information.)
