LD39115Jxx LD39115SJxx 150 m A low quiescent current low noise voltage regulator .. Features - - - Input voltage from 1.5 to 5.5 V Ultra low dropout voltage (80 m V typ. at 100 m A load) Very low quiescent current (20 µA typ. at no load, 35 µA typ. at 150 m A load, 1 µA max in off mode) Very low noise (33 µVRMS from 1 k Hz to 100 k Hz at VOUT = 1.8 V) Output voltage tolerance: ± 2.0% @ 25 °C 150 m A guaranteed output current Wide range of output voltages available on request: 0.8 V to 4.5 V with 100 m V step Logic-controlled electronic shutdown patible with ceramic capacitor COUT = 1 µF Internal current and thermal limit Flip-chip 4 bumps 0.8 x 0.8 mm. pitch Temperature range: -40 °C to 125 °C Flip-chip 4 - - - - - - - - - Description The LD39115Jxx provides 150 m A maximum current from an input voltage ranging from 1.5 V to 5.5 V with a typical dropout voltage of 80 m V. It is stablized with a ceramic capacitor. The ultra low drop voltage, low quiescent current and low noise Features make it suitable for low power batterypowered applications. Power supply rejection is 65 d B at low frequencies and starts to roll off at 10 k Hz. An enable logic control function puts the LD39115Jxx in shutdown mode allowing a total current consumption lower than 1 µA. The device also includes a short-circuit constant current limiting and thermal protection. Applications - - - Mobile phones Personal digital assistants (PDAs) Cordless phones and similar battery-powered systems Table 1.
