TPL9052/TPL9052-S Ultra-low Noise LDO

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 1μF or larger ceramic output capacitor.The TPL9052 series products have high PSRR with 88 dB at 10 kHz and 8.6μVRMS 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.
