Product Overview


The LM2842XMK-ADJL/NOPB is a Step-down DC/DC Regulator with a wide input range from 4.5V-42V and suitable for a wide range of applications such as power conditioning from unregulated sources. This regulator features a low RDSON (0.9Ω typical) internal switch for maximum efficiency (85% typical). Operating frequency is fixed at 550kHz (X version) and 1.25MHz (Y version) allowing the use of small external components while still being able to have low output voltage ripple. Soft-start can be implemented using the shutdown pin with an external RC circuit allowing the user to tailor the soft-start time to a specific application. This LM2842 regulator is available in adjustable output voltage version.
  • 16µA Typical Low shutdown
  • Short-circuit protection
  • Internally compensated
  • Soft-start circuitry
  • Green product and no Sb/Br

Applications

Power Management
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
