Product overview

Description

The LD59030 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 135 mV at VOUT = 3.3 V. It is available in DFN4 1x1 package, allowing the maximum space saving.
The device works 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 and output current fold-back protection, make the LD59030 suitable for low power battery-operated applications.
An enable logic control function puts the LD59030 in shutdown mode allowing a total current consumption lower than 0.03 µA.
  • All features

    • Input voltage from 1.5 to 5.5 V
    • Ultra low dropout voltage (135 mV typ. at 300 mA load)
    • Very low quiescent current (28 µA typ. at no load, 0.03 µA typ. in off mode)
    • Internal current fold-back
    • Output voltage tolerance: ± 1 % @ 25 °C
    • 300 mA guaranteed output current
    • High PSRR: 75 dB@1 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
    • Thermal protection
    • Available in DFN4 1x1
    • Operating temperature range: -40 °C to 125 °C
