LSP2015CAAD150

LSP2015 300mA CMOS LDO General Description The LSP2015 is a low dropout linear regulator (LDO) family with 300mA output current. The output voltage can be fixed or adjustable, and are stable with 1.0uF or higher value ceramic capacitors. The LSP2015 family provides several protections, such as over current protection (OCP), short circuit protection (SCP) and over temperature protection (OTP) to protect themselves from fault application conditions. This family of LDOs have many different packages and pin assignments. The users can refer the ordering information of this datasheet to choice the most suitable LDOs for their applications. Features • Operating Input Voltage : 2.2V~5.5V • • Has Fixed Output Voltage (Fixed-VOUT) And Adjustable Output Voltage (Adj-VOUT) Options Fixed Output voltage range: 1.0V to 4.1V by 0.1V steps • Output current is up to 300 mA • Built-in Over Current Protection (OCP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP) • Package : SOT23-3L, SOT23-5L, SC82-4L, SC70-5L, SOT89-3L and TO92-3L Packages Applications • • • Portable Electronics Wireless Applications Battery Power Devices Please be aware that an Important Notice concerning availability, disclaimers, and use in critical applications of LSC products is at the end of this document.
