The TPL803233-S5TR from 3PEAK is a fixed 3.3V low dropout linear regulator delivering up to 300mA. Its low 160 µA quiescent current and high PSRR (79dB at 120Hz) make it ideal for battery-powered and noise-sensitive applications. Housed in a compact SOT-23-5 package, it offers a dropout voltage of just 0.55V at full load, ensuring efficient operation from low input supplies.
- Extended Battery Life: Ultra-low 160 µA quiescent current minimizes standby power draw in portable devices.
- Clean Power Delivery: High PSRR of 79dB at 120Hz and 41dB at 1MHz rejects supply noise for sensitive analog circuits.
- Compact Footprint: SOT-23-5 package saves PCB space for space-constrained designs.
- Reliable Operation: Low 0.55V dropout at 300mA ensures stable output even with input voltage headroom as low as 3.85V.
