- Ultra-low 1.1 V dropout voltage enabling efficient operation from 2.7 V input
- Excellent 0.001% load regulation for stable output under varying current demands
- Compact 8-pin MSOP package for space-constrained portable and embedded designs
Applications
The TPS77316DGKG4 is ideal for powering low-voltage DSPs, FPGAs, and microcontrollers in portable and battery-operated equipment where tight voltage accuracy and low dropout are essential. It suits post-regulation stages in systems converting from 3.3 V or 5 V rails down to 1.6 V for core logic supplies. Its low quiescent current and small MSOP footprint make it a strong choice for space-critical IoT node and wireless sensor designs.

Frequently Asked Questions
What is the output voltage and current rating of the TPS77316DGKG4?
The TPS77316DGKG4 provides a fixed 1.6 V regulated output with a maximum output current of 250 mA. The output voltage accuracy is ±2%, ensuring tight regulation suitable for powering precision digital logic and low-voltage processor cores.
What is the dropout voltage of the TPS77316DGKG4 and why does it matter?
The TPS77316DGKG4 has a maximum dropout voltage of 1.1 V, meaning the input supply must be at least 2.7 V to maintain the 1.6 V regulated output. Low dropout voltage is critical for battery-powered designs where input voltage decreases as the battery discharges, extending usable battery life.
What is the maximum input voltage for the TPS77316DGKG4?
The TPS77316DGKG4 supports a maximum absolute input voltage of 13.5 V, providing wide input compatibility for use in systems powered from 5 V, 9 V, or 12 V supply rails with robust tolerance against transient voltage spikes.
What package does the TPS77316DGKG4 come in?
The TPS77316DGKG4 is packaged in an 8-pin MSOP (S-PDSO-G8) surface-mount package. The MSOP is significantly smaller than standard SOIC-8, making it ideal for compact PCB designs in handheld devices, wearables, and miniaturized industrial electronics.
Can the TPS77316DGKG4 replace other fixed 1.6 V LDO regulators?
The TPS77316DGKG4 can replace other fixed 1.6 V LDOs in the TPS773xx family and similar 8-pin MSOP devices from other manufacturers, provided pin compatibility is confirmed. Verify dropout voltage, quiescent current, and enable polarity before substitution to ensure drop-in replacement without redesign.
