LP2950 100mA低压差线性调节器
The LP2950 is a 100mA CMOS linear voltage regulator offered in an SC-70 package that reduces board space requirements by 50% over a SOT-23 package. The LP2950/4 features low dropout voltage (250mV at 100mA ), low ground current (135μA at full load) and low, 65μA quiescent current. Designed specifically for hand-held, battery powered devices, the device includes an enable/shutdown pin. Regulator ground current increases only slightly in dropout to extend battery life. The LP2950/4 is offered in an industry standard 5-pin SC-70 package. LP2950/4 is available in 1.8V, 2.5V, 2.7V, 2.85V, 3.0V, 3.3V and 5.0V fixed output voltages.
