Device Overview

Summary

The TC1303C 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 outputs of the Buck and LDO regulators.

Additional Features
    • Independent 300mA Low-Dropout Regulator
    • Power-good Monitor on the Buck and 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
