LM5009A Datasheet (National Semiconductor) - 150 mA Constant On-Time Buck Switching Regulator

LM5009A, 150 mA Constant On-Time Buck Switching Regulator

The LM5009A is a functional variant of the LM5009 COT Buck Switching Regulator.

The functional differences of the LM5009A are: The minimum input operating voltage is 6 volts, the on-time equation is slightly different, and the requirement for a minimum load current is removed.
