LMR12010XMKX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LMR12010XMKX/NOPB is a Simple Switcher step-down DC/DC switching regulator manufactured by Texas Instruments. It operates with an input voltage range of 3 V to 20 V and provides a regulated output current of 1 A. The device integrates a 1.6 MHz fixed switching frequency, enabling the use of small external components. It supports adjustable output voltages from 800 mV to 17 V. Key electrical parameters include a quiescent current of 1.5 mA and a shutdown feature for power management. The component is housed in a SOT-23-THIN-6 package and is rated for operation between -40°C and +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a high-side N-channel MOSFET switch within a compact footprint.
• Features a fixed 1.6 MHz switching frequency to minimize passive component size.
• Includes internal soft-start circuitry to limit inrush current during startup.
• Provides comprehensive protection against overcurrent, thermal overload, and undervoltage lockout.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable consumer electronics requiring efficient power conversion
• Industrial control systems with 12 V or 24 V supply rails
• Embedded computing modules needing stable low-voltage regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging configuration distinct from cut-tape variants. Confirm the 'NOPB' designation ensures lead-free and RoHS compliance status as per manufacturer specifications. Cross-reference the full part number against official datasheets to ensure compatibility with required operating temperature ranges and pinout configurations before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this regulator when designing space-constrained circuits that require a 1 A output capability from a 20 V maximum input source. The 1.6 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure the application does not exceed the 1 A continuous current limit or the thermal dissipation capabilities of the SOT-23-THIN-6 package under expected ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LMR12010 family of Simple Switcher regulators, designed for general-purpose buck conversion applications. It shares architectural similarities with other devices in the series but is distinguished by its specific 1 A current rating and 20 V input tolerance. The family targets cost-sensitive designs requiring high efficiency in small form factors.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct functional substitutes within the same package may include other LMR12010 variants with different packaging suffixes. Verify pin-to-pin compatibility and electrical parameter alignment with alternative Texas Instruments buck regulators offering similar input voltage and current specifications.
