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.
Features:
500 mA synchronous inductor-based dc-dc BUCK converter + 300 mA LDO with Power Good Output.
Output voltages set to Buck VOUT1 = 1.8V, LDO VOUT2 = 2.7V
