概要
Description
TPS629206QDRLRQ1 is a Texas Instruments low-dropout regulator (LDO) in the TPS629206 family. It’s designed for portable and space‑constrained applications, delivering a regulated output with very low quiescent current for long battery life. Key features typically include enable control, protection against overcurrent and thermal shutdown, reverse-current protection, and stable output with good PSRR and low noise. The QDRLRQ1 suffix denotes the specific packaging and tape/reel options for RoHS-compliant delivery (exact package type is shown in the datasheet). Typical use cases are powering microcontrollers, sensors, and other analog/digital blocks in battery-powered devices. For exact electrical specs (input range, output voltage options, maximum output current), pinout, and recommended external capacitors, refer to the TPS629206 datasheet and TI product page.
Features
Here are the typical features of the TPS629206QDRLRQ1 (DC-DC buck regulator in QDRLRQ1 package):
- Synchronous step-down DC-DC converter with integrated high-side/low-side MOSFETs
- Input voltage range: 1.8 V to 5.5 V
- Output: adjustable (0.8 V to ~5.0 V) with feedback; fixed-output variants available
- High efficiency with current-mode control for fast transient response
- Enable pin for easy shut down
- Programmable soft-start to limit inrush
- Protective features: overcurrent/short-circuit protection and thermal shutdown
- Power-good/reset indication
- Low quiescent current for improved battery life (especially in light load)
- Compact 8-pin QFN/SOIC-like package (QDRLRQ1 code) designed for space-constrained apps
Note: exact output ranges and performance specs vary by variant; check the datasheet for precise numbers.
