LMR14006XDDCR

Voltage Regulators - DC DC Switching Regulators Overview

The LMR14006XDDCR is a SIMPLE SWITCHER buck regulator from Texas Instruments, housed in a SOT-23-THIN-6 package. It supports an input voltage range of 4 V to 40 V and delivers up to 600 mA output current. The adjustable output voltage spans from 800 mV to 30 V. Operating with a fixed switching frequency of 1.1 MHz, the device maintains a typical quiescent current of 28 uA. It functions within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DDCR confirms the reel packaging format required for automated assembly processes. Ensure the X variant matches the intended 1.1 MHz switching frequency specification for your filter design. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages reach 40 V but space constraints necessitate a SOT-23 footprint. The 1.1 MHz frequency balances efficiency and size against lower frequency alternatives. Verify that the 600 mA load requirement does not exceed thermal limits in the target enclosure environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR14006 series of non-synchronous buck converters. It shares architectural similarities with the LMR14003 and LMR14006Y variants, differing primarily in switching frequency and maximum output voltage capabilities. The family targets cost-sensitive, space-constrained power management needs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR14006XDDCT serves as the tape-and-reel alternative to the cut-tape version. LMR14006YDDCR offers a higher switching frequency of 2.1 MHz for smaller inductors. Cross-reference pinouts and thermal characteristics carefully when substituting.
