LMR10515 - Texas Instruments

LMR10515 Step-Down Voltage Regulator

The LMR10515 regulator is a monolithic, high frequency, PWM step-down DC/DC converter in a 5pin SOT-23 and a 6-pin WSON package. It provides all the active functions to provide local DC/DC conversion with fast transient response and accurate regulation in the smallest possible PCB area. With a minimum of external components, the LMR10515 is easy to use. The .
