LD59030DTPU18R STMicroelectronics

LD59030 Datasheet 300 mA very low dropout linear regulator IC Features Input voltage from 1.5 to 5.5 V Ultra low dropout voltage (135 mV typ. at 300 mA load) DFN4 1x1 Very low quiescent current (28 A typ. at no load, 0.03 A 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 C = 0.47 F OUT Thermal protection Available in DFN4 1x1 Operating temperature range: -40 C to 125 C Description The LD59030 high accuracy voltage regulator provides 300 mA of maximum current Maturity status link from an input voltage ranging from 1.5 V to 5.5 V, with a typical dropout voltage of LD59030 135 mV at V = 3.3 V. OUT 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 A.
