LDK130 300 mA low quiescent current very low noise LDO Datasheet - production data Applications * Mobile phones * Personal digital assistants (PDAs) * Cordless phones and similar battery-powered systems 627/ ')1 [PP * Digital still cameras Description 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. 627/ It is stabilized with a ceramic capacitor on the output. Features * Input voltage from 1.9 to 5.5 V * Very low dropout voltage (100 mV typ. at 100 mA load) * Low quiescent current (max. 120 A, 1 A in OFF mode) * Very low noise * Output voltage tolerance: 2.0 % @ 25 C The very low drop voltage, low quiescent current and low noise features make it suitable for low power battery-powered applications. An enable logic control function puts the LDK130 in shutdown mode allowing a total current consumption lower than 1 A. The device also includes a 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 F * Internal current and thermal limit * Available in SOT23-5L, SOT323-5L and DFN6 (1.2 x 1.3 mm) packages * Temperature range: -40 C to 125 C March 2014 This is information on a product in full production.
