LDK130PU33R

LDK130 300 mA low quiescent current very low noise LDO (automotive for SOT23-5L package) Datasheet - production data Applications • Mobile phones • Portable consumer and industrial devices • Cordless phones and similar battery-powered systems 627/ ')1[PP DFN6 1.2x1.3 • Automotive P.O.L. • A.D.A.S. Description 627/ The LDK130 low drop voltage regulator provides 300 mA of maximum current from an input supply voltage in the range of 1.9 V to 5.5 V, with a typical dropout voltage of 100 mV. Features It is stabilized with a ceramic capacitor on the output. • AEC-Q100 qualified (automotive grade 1, SOT23-5L package) • Input voltage from 1.9 to 5.5 V • Very low-dropout voltage (100 mV typ. at 100 mA load) • Low quiescent current (typ. 30 µA, 1 µA in OFF mode) • Very low noise • Output voltage tolerance: ± 2.0% at 25 °C The very low drop voltage, low quiescent current and low-noise features make it suitable for lowpower battery-powered applications. An enable logic control function puts the LDK130 in shutdown mode allowing a total current consumption lower than 1 µA. The device also includes short-circuit constant current limiting and thermal protection. • 300 mA guaranteed output current • Wide range of fixed output voltages available on request: from 0.8 V to 3.5 V with 100 mV step • Adjustable version: from 0.8 V to VIN - Vdrop • Logic-controlled electronic shutdown • Compatible with ceramic capacitor COUT = 1 µF • Internal current and thermal limit • Available in SOT23-5L, SOT323-5L and DFN6 1.2x1.3 packages • Temperature range: -40 °C to 125 °C March 2020 This is information on a product in full production.
