1 / 30 page June 2015 DocID025316 Rev 3 1/30 This is information on a product in full production. www.st.com LD39020 200 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 (200 mV typ. at 200 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) 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 DFN 1x1-4L and SOT23-5L Operating temperature range: -40 °C to 125 °C Applications Mobile phones Personal digital assistants (PDAs) Digital still cameras (DSC) Cordless phones and similar battery- powered systems Portable media players Description The LD39020 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 DFN 1x1-4L and SOT23-5L packages, 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 LD39020 suitable for low power battery- operated applications. An enable logic control function puts the LD39020 in shutdown mode allowing a total current consumption lower than 0.1 µA. Constant current and thermal protection are provided. DFN1x1-4L SOT23-5L |
