Electrical Regulators

Linear Regulators offer low dropout.

Models LP3883/2/1 CMOS dual-input, voltage regulators enable high efficiency linear conversion from 1.8-1.5 V and 1.2 V for notebook and set-top box applications, while consuming low quiescent current of only 3 mA. Power input may be fed independently from high current supply facilitating conversion from input rails of less than 2.5 V. Dropout voltage for Models LP3883/2/1 is typically 210 mV/110...
