What are the key features of TPS77401MDGKREP?
- Ultra-low 0.2 V dropout voltage allows regulation from supply rails only slightly above output voltage, maximizing battery life in portable systems
- Adjustable output voltage configuration covers a wide range of target voltages using two external resistors, eliminating need for fixed-output variants
- Integrated power-good output flag provides system supervisory function, signaling downstream logic when output voltage is within regulation, simplifying sequencing circuits
- Excellent 0.05 %/V line regulation and 0.06 % load regulation ensure stable output under varying input and load conditions for noise-sensitive analog circuits
What is TPS77401MDGKREP used for?
The TPS77401MDGKREP is designed for post-regulation of switching converter outputs in portable electronics, providing low-noise, well-regulated supply rails for analog front ends, RF modules, and precision sensors. Its power-good output is used in processor and FPGA power sequencing circuits to ensure all rails are established before releasing reset signals. The device also serves in space and defense electronics where the enhanced product grade guarantees extended reliability and traceability across the -55 to 125 °C military temperature range.

Frequently Asked Questions
What is the dropout voltage of the TPS77401MDGKREP?
The TPS77401MDGKREP has a nominal dropout voltage of 0.2 V. This very low dropout means the device can maintain regulation when the input voltage is only 200 mV above the set output voltage, which is critical in battery-powered applications approaching end-of-discharge conditions.
What does the power-good output on the TPS77401MDGKREP do?
The power-good output is an open-drain flag that goes high when the output voltage reaches its regulated level. System designers use this signal to drive processor reset pins or enable logic, ensuring downstream circuits do not power up until the LDO output is fully established, preventing spurious behavior during power-up sequences.
Is the TPS77401MDGKREP a fixed or adjustable output regulator?
The TPS77401MDGKREP is an adjustable output LDO regulator. The output voltage is set by an external resistor divider connected to the adjust pin, allowing designers to program any output voltage within the device's supported range rather than being limited to a fixed voltage, providing design flexibility across multiple product variants.
What is the input voltage range of the TPS77401MDGKREP?
The TPS77401MDGKREP accepts input voltages from 2.7 V minimum to 10 V maximum, making it compatible with single-cell lithium-ion batteries, USB 5 V rails, and regulated 3.3 V or 5 V bus supplies. This range covers the majority of portable and industrial low-voltage power architectures.
What does the 'Enhanced Product' designation mean for the TPS77401MDGKREP?
The 'Enhanced Product' designation indicates this part is manufactured with additional process controls, screening, and documentation to meet the requirements of high-reliability markets such as aerospace, defense, and industrial applications with extended life cycle needs. It provides greater traceability and consistency compared to standard commercial-grade parts.
