Key Features
- Ultra-low-noise output with high PSRR performance, critical for RF, ADC, and precision analog supply rails that demand a clean 1.8 V regulated voltage
- 300 mA output current with a 200 mV maximum dropout voltage from a 2.1 V to 6 V input range, supporting low-headroom battery-powered designs
- Miniature 4-ball BGA (S-XBGA-B4) package with 0.013% maximum load regulation enables dense PCB layouts for wearable and IoT applications
Applications
The TPS7A2018PYCKR is used to power noise-sensitive analog front-ends, RF transceivers, and precision ADCs where supply ripple and noise must be minimized to avoid degrading dynamic range. Its ultra-low quiescent current and 300 mA output make it suitable for always-on battery-powered IoT sensors and wearable devices that operate from a 2.1 V to 6 V cell. High-PSRR requirements in software-defined radio (SDR) modules and wireless communication cards also drive adoption of this device for its ability to suppress switching noise from upstream regulators.

Frequently Asked Questions
What is the maximum dropout voltage of TPS7A2018PYCKR at 300 mA, and how does that affect battery-powered design choices?
The TPS7A2018PYCKR has a maximum dropout voltage of 200 mV at its rated 300 mA output current, meaning a 2.1 V input is sufficient to regulate an 1.8 V output without dropping out of regulation. This low dropout allows the device to extract usable energy from a Li-ion cell as it discharges toward 2.1 V, extending the operational window of battery-powered wearables and IoT sensors compared to regulators with 400 mV or higher dropout voltages.
For an RF transceiver supply requiring high PSRR, how does TPS7A2018PYCKR reduce switching noise interference?
The TPS7A2018PYCKR's high PSRR attenuates ripple and noise injected by upstream switching regulators before they reach the RF transceiver supply pin, preventing frequency spurs from appearing in the transmitted or received spectrum. Combined with its ultra-low-noise output voltage characteristic and 0.2106% maximum line regulation, the device keeps the RF supply clean enough to meet the phase noise and EVM requirements of modern communication standards, even when powered from a noisy DC/DC converter output.
In which precision measurement designs does the 0.013% load regulation of TPS7A2018PYCKR provide a measurable accuracy advantage?
Precision data acquisition systems using 16-bit or 24-bit SAR or delta-sigma ADCs benefit most from the 0.013% maximum load regulation, because supply voltage variation directly introduces gain error in the ADC reference or analog input range. At 300 mA capacity and 0.013% load regulation, the TPS7A2018PYCKR keeps the supply deviation well below 1 LSB for most 16-bit ADC reference voltages, preventing supply-induced measurement errors in laboratory instruments, medical monitors, and industrial weigh-scale front-ends.
