TPS561201DDCT Description

The TPS561201 and TPS561208 are 1-A synchronous step-down converters in a SOT-23 package that are straightforward and easy to use.The devices have been tuned to function with the fewest possible external components and to have a low standby current. With no external compensation components, these switch mode power supply (SMPS) devices use D-CAP2 mode control to provide a fast transient response and support both low equivalent series resistance (ESR) output capacitors such as specialized polymer and ultra-low ESR ceramic capacitors.
