LDK120PU33R

LDK120 200 mA low quiescent current very low noise LDO Datasheet - production data Applications  Mobile phones  Personal digital assistants (PDAs) 627/ ')1[PP  Cordless phones and similar battery-powered systems  Digital still cameras Description The LDK120 low drop voltage regulator provides 200 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. 100 µA, 1 µA 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 LDK120 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.  200 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 (1.2 x 1.3 mm) packages  Temperature range: -40 °C to 125 °C January 2018 This is information on a product in full production.
