TPL905218-S5TR

The TPL9052 series are 500 mA high power supply rejection ratio (PSRR), ultra-low noise, low dropout linear regulators with high output accuracy. The TPL9052 series supports a fixed output voltage range of 0.9 V to 5 V and remains stable with ceramic output capacitors of 1 μF or larger. The TPL9052 series features 88 dB high PSRR at 10 kHz and ultra-low noise of 8.6 μVRMS. These characteristics make the TPL9052 series ideal for noise-sensitive applications with high upstream power supply noise, such as high-performance analog devices or high-definition imaging equipment. The TPL9052 series integrates protection features: output reverse current protection, output short-circuit protection, over-temperature protection, and overload protection. All these features significantly improve system reliability and simplify circuit design under varying operating conditions. The TPL9052 series is available in SOT23-5 and DFN1X1-4 packages, with a guaranteed operating junction temperature range (TJ) from -40°C to +125°C.
