LD56100
LD56100 is 1A very low dropout fast transient ultra-low noise linear regulator manufactured by STMicroelectronics.
Features - Input voltage from 1.8 to 5.5 V - Ultra-low dropout voltage (120 m V typ. at 1 A load and VOUT = 3.3 V) - Very low quiescent current (100 µA typ. at no-load, 0.03 µA typ. in off mode) - Output voltage tolerance: ± 1% from -40 °C to +85 °C - Ultra-low Noise: 13 µV RMS Noise from 10 Hz to 100 k Hz at VOUT = 3.0 V - High PSRR (70 d B@1 k Hz) - Wide range of output voltages available on request: from 1.0 V up to 5.0 V in 50 m V step - Logic-controlled electronic shutdown - Internal soft-start - Optional output voltage discharge feature - patible with ceramic capacitor COUT = 1 µF - Internal current limit foldback and thermal protections - Available in DFN8 (1.2 x 1.6 mm) - Operating temperature range: -40 °C to 125 °C Applications - Mobile phones - Tablets - Battery-powered systems - Camera supply Description The LD56100 high accuracy voltage regulator provides 1 A of current from an input voltage ranging from 1.8 V to 5.5 V, with a typical dropout voltage of 120 m V. It is available in DFN8 (1.2 x 1.6 mm) 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 fast transient response, together with the internal soft-start circuit, make the LD56100 suitable for low power battery-operated applications. An enable logic control function puts the LD56100 in shutdown mode allowing a total current consumption lower than 0.1 µA. Short-circuit protection with current limit foldback and thermal protection are also included.
