STMicroelectronics LDK120M33R, 1 Low Dropout Voltage, Voltage Regulator 200mA, 3.3 V 5-Pin, SOT-23

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. It is stabilized with a ceramic capacitor on the output. 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.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 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 Applications Mobile phones Personal digital assistants (PDAs) Cordless phones and similar battery-powered systems Digital still cameras
