This device is an excellent choice for use in battery-powered application such as cordless telephones, radio-control systems, and portable computers. The LM2950G features a very low quiescent current (75uA typ.) and a very low drop output voltage (typ. 40mV at a light load and 380mV at 100mA). Furthermore, a tight initial Output voltage tolerance of 0.5% Typ., an extremely good load and line regulation of 0.05% Typical, and a very low output temperature coefficient - all that makes the LM2950G very useful as a lowpower voltage reference.

Note 2 : The regulation is measured at a constant junction temperature using pulse testing with a low duty cycle. Changes in the output voltage due to heating effects are covered under the specification for thermal regulation. Note 3 : The dropout voltage is defined as the input-to-output differential, at which the output voltage drops 100mV below its nominal value measured at 1V differential. At very low values of a programmed output voltage, the minimum input supply voltage 2V (2.3V over temperature) must be taken into account.
