LD39030 300 mA very low quiescent current linear regulator IC Datasheet - production data Features  Input voltage from 1.5 to 5.5 V  Ultra low dropout voltage (300 mV typ. at 300 mA load)  Very low quiescent current (20 µA typ at no load, 0.03 µA typ in off mode)  Output voltage tolerance: ±0.5 % (A version) or ± 2.0 % @ 25 °C (standard version)  300 mA guaranteed output current  High PSRR (80 dB@1 kHz, 50 db@100 kHz)  Wide range of output voltages available on request: from 0.8 V up to 5.0 V in 50 mV step  Logic-controlled electronic shutdown  Internal soft-start  Optional output voltage discharge feature  Compatible with ceramic capacitor COUT = 0.47 µF  Internal constant current and thermal protections  Available in DFN4 1x1  Operating temperature range: -40 °C to 125 °C Applications  Mobile phones  Tablets  Digital still cameras (DSC)  Cordless phones and similar battery- powered systems  Portable media players Description The LD39030 high accuracy voltage regulator provides 300 mA of maximum current from an input voltage ranging from 1.5 V to 5.5 V, with a typical dropout voltage of 300 mV. It is available in DFN4 1x1 package, allowing the maximum space saving. The device is stabilized with a ceramic capacitor on the output. The ultra low drop voltage, low quiescent current and low noise features, together with the internal soft-start circuit, make the LD39030 suitable for low power batteryoperated applications. An enable logic control function puts the LD39030 in shutdown mode allowing a total current consumption lower than 0.1 µA. Constant current and thermal protection are provided.
