LM8801TMX-1.2/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM8801TMX-1.2/NOPB is a synchronous step-down DC-DC converter manufactured by Texas Instruments, originally part of the National Semiconductor portfolio. It operates with an input voltage range of 2.3V to 5.5V and provides a fixed output of 1.2V at up to 600mA. The device integrates a 6MHz switching frequency for compact passive design. It features a DSBGA-6 package and supports shutdown mode with low quiescent current.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous rectification architecture for high efficiency
• Fixed 6MHz switching frequency reduces external component size
• Integrated soft-start and current limit protection
• Shutdown mode minimizes standby power consumption

Voltage Regulators - DC DC Switching Regulators Applications

• Portable mobile devices requiring efficient power management
• Battery-powered consumer electronics
• Embedded systems with strict space constraints
• General-purpose point-of-load regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation carefully, as the component originates from National Semiconductor but is now distributed under Texas Instruments branding. Confirm the suffix 'NOPB' indicates lead-free and RoHS compliance. Ensure the specific output voltage variant matches the design requirement, as the LM8801 family offers multiple fixed voltage options.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for low-voltage applications. The 6MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Verify that the load current does not exceed 600mA and that the input voltage remains within the 2.3V to 5.5V range for proper operation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM8801 series of high-precision synchronous buck converters. It was developed by National Semiconductor before its acquisition by Texas Instruments. The series is designed for mobile applications where board space and battery life are critical constraints.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM8801 variants with different fixed output voltages, such as LM8801TME-2.9/NOPB or LM8801TMX-1.2/NOPB. Cross-reference pinouts and thermal characteristics to ensure compatibility with existing PCB layouts.
