1 / 24 page March 2009 Rev 1 1/24 24 LD39050xx 500 mA low quiescent current low noise voltage regulator Features ■ Input voltage from 1.5 to 5.5 V ■ Ultra low dropout voltage (200 mV typ. at 500 mA load) ■ Very low quiescent current (20 µA typ. at no load, 100 µA typ. at 500 mA load, 1 µA max in off mode) ■ Very low noise without bypass capacitor ■ Output voltage tolerance: ± 2.0 % @ 25 °C ■ 500 mA guaranteed output current ■ Wide range of output voltages available on request: 0.8 V to 4.5 V with 100 mV step and ADJ from 0.8 V ■ Logic-controlled electronic shutdown ■ Compatible with ceramic capacitor COUT = 1 µF ■ Internal current and thermal limit ■ Package DFN6 (3 x 3 mm) ■ Temperature range: -40 °C to 125 °C Description The LD39050 provides 500 mA maximum current from an input voltage ranging from 1.5 V to 5.5 V with a typical dropout voltage of 200 mV. Stability is provided using ceramic capacitors. The ultra low drop-voltage, low quiescent current and low noise features make it suitable for low power battery-powered applications. Power supply rejection is 65 dB at low frequencies and starts to roll off at 10 kHz. An Enable logic control function puts the LD39050 in shut-down mode allowing a total current consumption lower than 1 µA. The device also includes short-circuit constant current limiting and thermal protection. Typical applications are mobile phones, personal digital assistants (PDAs), cordless phones and similar battery-powered systems. DFN6 (3 x 3 mm) Table 1.
