User Guide:

The TC1303B combines a 500mA synchronous buck regulator and a 300mA low-dropout (LDO) regulator with a power-good monitor to provide a highly integrated solution for applications that require multiple supply voltages. The power-good function monitors the output of the LDO regulator.



  • Independent 300mA Low-Dropout Regulator
  • Power-good Monitor on the LDO Output with 300mS Delay
  • Both Outputs Internally Compensated
  • Independent Shutdown for the Buck and LDO Outputs
  • Automatic PWM to PFM mode transition
  • Small 10-Pin 3x3 DFN and MSOP
  • Undervoltage Lockout (UVLO)
  • Output Short Circuit and Overtemperature Protection
