Frequently Asked Questions
What is the output voltage range of the TPS77401DGKG4?
The TPS77401DGKG4 is an adjustable LDO regulator with an output voltage range of 1.5V to 5.5V. The output voltage is set by an external resistor divider connected to the ADJ pin, allowing flexible configuration to suit various power rail requirements in embedded and analog system designs.
What is the dropout voltage of the TPS77401DGKG4?
The TPS77401DGKG4 has a nominal dropout voltage of 1V, meaning the input voltage must be at least 1V higher than the desired output voltage to maintain regulation. This low dropout characteristic extends battery life in portable applications and enables efficient post-regulation in systems with constrained input headroom.
What package does the TPS77401DGKG4 come in and is it RoHS compliant?
The TPS77401DGKG4 is housed in an 8-pin VSSOP package (JESD-30 code S-PDSO-G8) with e4 JEDEC moisture sensitivity rating. The G4 suffix confirms RoHS-compliant lead-free solder construction, meeting environmental compliance requirements for commercial and industrial product applications.
What are the line and load regulation specifications of the TPS77401DGKG4?
The TPS77401DGKG4 offers a maximum line regulation of 0.05%/V and a maximum load regulation of 0.06%, indicating excellent output voltage stability under varying input voltages and load current conditions. These specifications make it suitable for precision analog circuits and noise-sensitive digital applications.
What are suitable alternatives to the TPS77401DGKG4?
Functionally similar alternatives include the TPS77301 (300mA adjustable LDO), LP2981 (100mA fixed LDO in SOT-23), and LM1117 (800mA adjustable LDO). When selecting a replacement, confirm that the alternative meets the same dropout voltage, output current, package, and regulation accuracy requirements to maintain circuit performance.
