General Description
SC1517-5 General Description
The SC1517-5 is pin compatible with LTC1517-5. This versatile charge pump produces a regulated 5V output from an input voltage ranging from 2.7V to 5V. The Extremely low operating current (typically 10A with no load) prolongs battery usage time. The small device footprint and the low external parts count (one 0.1F flying capacitor and two small bypass capacitors at VIN and VOUT) make the part ideally suited for compact circuit design.
The SC1517-5 charge pump can be used for applications that require up to 20mA (3V < VIN < 5V) of output current, while providing a regulated 5V output voltage. During short circuit a current limit circuitry provides protection, while the thermal shutdown capability cycles VOUT to prevent device failure. The SC1517-5 is available in a 5 lead SOT-23 package.
