Key Features
- Ultra-low 50 mV typical dropout voltage enabling efficient operation from near-rail input supplies down to 0.8 V
- Adjustable output voltage with 0.03%/V line regulation for precise point-of-load power in noise-sensitive analog designs
- Compact 10-pin WSON (3 mm x 3 mm) footprint with excellent thermal performance for space-constrained PCB layouts
Applications
The TPS74701DRCR is designed for post-regulator and point-of-load applications in processors, FPGAs, and DSPs where a low-noise, tightly regulated supply is critical. Its adjustable output and ultra-low dropout voltage make it well suited for powering analog front-ends, RF circuits, and memory arrays in portable industrial instruments and communications equipment. The device also serves as a low-ripple secondary rail in multi-rail power trees fed from a switching pre-regulator.

Frequently Asked Questions
What is the minimum input-to-output voltage differential the TPS74701DRCR can sustain at full rated current?
The TPS74701DRCR achieves a typical dropout voltage of only 50 mV at its full rated output current, with a maximum specification of 120 mV under worst-case conditions. This ultra-low dropout means the device can maintain a regulated output from an input supply that is only 120 mV above the set output voltage, making it ideal for converting a 3.3 V rail to a 3.2 V precision supply without excessive power dissipation or thermal stress.
How does the TPS74701DRCR's adjustable output voltage work, and what resistor network sets the output to 1.8 V?
The TPS74701DRCR uses an external resistor divider connected from the output to the ADJ pin to set output voltage, with the internal reference voltage of 0.8 V at the ADJ node. To set 1.8 V output, a standard 100 kΩ top resistor and approximately 80 kΩ bottom resistor achieve the target, calculated from Vout = 0.8 V × (1 + R1/R2). The 0.03%/V line regulation ensures the output stays within ±1% across the full 0.8 V to 5.5 V input range.
In which applications does the TPS74701DRCR outperform a standard switching regulator despite lower efficiency?
The TPS74701DRCR outperforms switching regulators in noise-sensitive analog and RF applications because it produces no switching ripple—the output noise is typically below 50 µVRMS across a 10 Hz to 100 kHz bandwidth. Precision ADC reference rails, RF LNA bias supplies, and phase-locked loop (PLL) VCO supplies benefit from this clean output that a switching converter with its 200 mV peak-to-peak ripple could not match, even with heavy filtering. The trade-off in efficiency is acceptable when load currents are modest and supply rail headroom is tight.
What package does the TPS74701DRCR use, and how does the 10-pin WSON help with thermal dissipation?
The TPS74701DRCR is housed in a 10-pin WSON package measuring 3 mm x 3 mm with an exposed thermal pad on the bottom. The exposed pad allows direct solder attachment to a PCB copper pour, reducing junction-to-board thermal resistance to approximately 18°C/W, which means the device can dissipate several hundred milliwatts without exceeding the 125°C maximum junction temperature even in confined enclosures operating up to 85°C ambient.
