LDK120 200 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 7 6 / 2 ) 1 PP Digital still cameras Description The LDK120 low drop voltage regulator provides 7 / 62 200 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. Features The very low drop voltage, low quiescent current Input voltage from 1.9 to 5.5 V and low noise features make it suitable for low Very low dropout voltage (100 mV typ. at 100 power battery-powered applications. mA load) An enable logic control function puts the LDK120 Low quiescent current (max. 100 A, 1 A in in shutdown mode allowing a total current OFF mode) consumption lower than 1 A. Very low noise The device also includes a short-circuit constant Output voltage tolerance: 2.0% 25 C 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 V -V IN drop Logic-controlled electronic shutdown Compatible with ceramic capacitor C = 1 F OUT 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 DocID023965 Rev 8 1/24 This is information on a product in full production. www.st.com 24Contents LDK120 Contents 1 Diagram . 3 2 Pin configuration 4 3 Typical application 5 4 Maximum ratings 6 5 Electrical characteristics . 7 6 Typical performance characteristics 9 7 Package mechanical data 14 8 Packaging mechanical data 20 9 Order codes . 22 10 Revision history . 23 2/24 DocID023965 Rev 8
