The TPL9052 series products are 500-mA high PSRR, ultra-low noise, low dropout linear regulators with high output accuracy. The TPL9052 series products support both fixed output voltage ranges from 0.9 V to 5 V and is stable with 1 μF or larger ceramic output capacitor. The TPL9052 series products have high PSRR with 88 dB at 10 kHz and 8.6 μVRMS ultra-low noise. These features make TPL9052 series products very suitable for noise-sensitive applications with high noise from previous stage power supply, such as high-performance analog devices, or high-definition imaging equipment. The TPL9052 series products integrate protection features: output reverse current protection, output shortage protection, over-temperature protection and overload protection. All these features significantly improve the system reliability and simplify circuitry design under different operating conditions. The TPL9052 series products provide SOT23-5, and DFN1X1-4 packages with guaranteed operating junction temperature range (TJ) from −40°C to +125°C.
