The TC1304 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 and can provide sequenced startup and shutdown.
Independent 300mA Low-Dropout Regulator
Power-good Monitor on the Buck and LDO Outputs
Sequenced Startup and Shutdown
Both Outputs Internally Compensated
Automatic PWM to PFM mode transition
Small 10-Pin 3x3 DFN and MSOP
Undervoltage Lockout (UVLO)
Output Short Circuit and Overtemperature Protection
The TC1303B Dual-Output Regulator with Power-Good Output Demo Board can be used to evaluate the TC1303B device over the input voltage range and output current range for both the synchronous buck regulator output and the low-dropout linear regulator output.
Test points are provided for input power, output loads, shutdown control and power-good monitoring.
