LDK220 200 mA low quiescent current and low noise LDO Datasheet - production data Applications Battery-powered equipment TV Set-top box PC and laptop Industrial Description The LDK220 is a low drop voltage regulator, which provides a maximum output current of 200 mA from an input voltage in the range of 2.5 V to 13.2 V, with a typical dropout voltage of 100 mV. A ceramic capacitor stabilizes it on the output. Features Input voltage from 2.5 to 13.2 V Very low-dropout voltage (100 mV typ. @ 100 mA load) Low quiescent current (typ. 55 µA, 1 µA in off mode) Low noise Output voltage tolerance: ± 2.0% @ 25 °C 200 mA guaranteed output current Wide range of output voltages available on request: fixed from 1.2 V to 12 V with 100 mV step and adjustable Logic-controlled electronic shutdown Compatible with ceramic capacitor COUT = 1 µF Internal current and thermal limit Available in SOT23-5L, SOT323-5L, SOT-89 and DFN6-1.2x1.3 packages Temperature range: -40 °C to 125 °C October 2016 The very low drop voltage, low quiescent current and low noise make it suitable for batterypowered applications. The enable logic control function puts the LDK220 in shutdown mode allowing a total current consumption lower than 1 µA. The device also includes a short-circuit constant current limiting and thermal protection.
