200 mA very low quiescent current linear regulator IC in (0.47x0.47) mA STSTAMP package

データシートのダウンロード

The LDBL20 high accuracy voltage regulator provides 200 mA of maximum current from an input voltage ranging from 1.5 V to 5.5 V, with a typical dropout voltage of 200 mV.

It is available in the new STSTAMP™ 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 LDBL20 suitable for low power battery-operated applications.

An enable logic control function puts the LDBL20 in shutdown mode with a total current consumption lower than 0.2 µA. Constant current and thermal protection are provided.

主な特徴

  • Output voltage tolerance: ± 1.5% @ 25 °C
  • 200 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 STSTAMP™ (0.47x0.47) mm² package
