100/300/600 mA Input Step-Down DC/DC
Regulator in Thin SOT-23
General Description
The LM2840, LM2841 and LM2842 are PWM DC/DC buck (step-down)
regulators.
With a wide input range from 4.
5V-42V, they are suitable for a wide range of applications such as power conditioning from unregulated sources.
They feature a low RDSON (0.
9Ω typical) internal switch for maximum efficiency (85% typical).
Operating frequency is fixed at 550 kHz (X version) and 1.
25 MHz (Y version) allowing the use of small external components while ...
