LM2842YMK-ADJL/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2842YMK-ADJL/NOPB is a SIMPLE SWITCHER step-down DC/DC regulator manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 42 V and delivers up to 600 mA output current. The device features an adjustable output voltage from 765 mV to 34 V and switches at a frequency of 1.25 MHz. It includes AEC-Q100 qualification for automotive applications, shutdown functionality, and a quiescent current of 1.3 mA. The component is housed in a SOT-23-THIN-6 package and supports operating temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Y' indicates the required automotive grade (AEC-Q100) and tape/reel packaging configuration. Confirm that the 'NOPB' designation ensures lead-free and RoHS compliance as per manufacturer specifications. Ensure the ordering part number matches the exact thermal and electrical requirements for the target application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 42 V is required in a minimal footprint. The 1.25 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. The integrated MOSFET simplifies the bill of materials. Consider the thermal performance within the SOT-23-THIN package for the expected load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2842 family of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM2842X series but differs in switching frequency and automotive qualification status. The Y suffix typically denotes specific automotive-grade screening and packaging variations within the broader product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2842XQMK/NOPB offers similar regulation but operates at 550 kHz and lacks explicit AEC-Q100 documentation in some contexts. LM2842YMKX/NOPB provides the same core specifications with reel packaging instead of cut tape.
