The LM2950 is a low power voltage regulator. This device excellent choice for use in battery poweredapplicaTIon such as cordless telephone, radio control systems, and portable computers.The LM2950 features very low quiescent current (75㎂ Typ.) and very low drop output voltage(Typ. 400㎷ at light load and 380㎷ at 100㎃).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, making the LM2950 useful as a low-power voltage reference.The error flag output feature is used as power-on reset for warn of a low output voltage, due tofollowing batteries on input. Other feature is the logic-compatible shutdown input which enable theregulator to be switched on and off. The LM2950 is available in 8-pin plastic packages.The regulator output voltage may be pin-strapped for a -XX volt or programmed from 1.24 volt to 29 voltswith external pair of resistors. The LM2950 is offered in 3-pin to-92 package compatible with otherfixed regulator.
