LM2841 - 100/300/600 mA Input Step-Down DC/DC Regulator

Download the LM2841 datasheet PDF. This datasheet also covers the LM2842 variant, as both devices belong to the same 100/300/600 ma input step-down dc/dc regulator family and are provided as variant models within a single manufacturer datasheet.

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.

LM2840/LM2841/LM2842/LM2840Q/LM2841Q/LM2842Q 100 / 300 / 600 mA Input Step-Down DC/ DC Regulator in Thin SOT-23 LM2840/LM2841/LM2842/ LM2840Q/LM2841Q/ LM2842Q August 23, 2011 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 still being able to have low output voltage ripple.
