LP3981 300-mA Ultra-Low-Dropout CMOS Voltage Regulator

Performance of the LP3981 device is optimized for battery-powered systems to deliver ultra-low-noise, extremely low dropout voltage, and low quiescent current. Regulator ground current increases only slightly in dropout, further prolonging the battery life. Power supply rejection is better than 60 d.

LP3981 Features

* 1 2.5-V to 6-V Input Range

* 300-mA Output Current

* 60-dB PSRR at 1 kHz

* ≤ 1-μA Quiescent Current When Shut Down

* Fast Turnon Time: 120 μs (typical) with CBYPASS = 0.01 µF

* 132-mV Typical Dropout with 300-mA Load

* 35-μVrms Output Noise Ov
