The TPL855633Q from 3PEAK is a high-performance 3.3V LDO linear regulator capable of delivering 500mA. It features an ultra-low quiescent current of 28 μA, making it ideal for battery-operated equipment. With excellent PSRR of 60dB at 1MHz, it ensures clean, stable power for noise-sensitive circuits. The 1V dropout at full load supports efficient operation across varying input conditions. Housed in a compact 28-ETSSOP package, this regulator balances power, efficiency, and size for demanding applications.
- Extended Battery Life: Ultra-low 28 μA quiescent current minimizes standby power draw.
- High Noise Immunity: 60dB PSRR at 1MHz rejects high-frequency interference for clean output.
- High Current Capacity: 500mA output supports a wide range of loads from sensors to microcontrollers.
- Reliable Under Load: 1V dropout at 500mA ensures stable regulation even with low input margins.
