TPL9032 Ultra-low Noise LDO-3peak

The TPL9032 series products are 300-mA high PSRR,ultra-low noise,low dropout linear regulators with high output accuracy.The TPL9032 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 TPL9032 series products have high PSRR with 87.9 dB at 10 kHz and 8.6μVRMS ultra-low noise.These features make TPL9032 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.Output shortage protection and thermal overload protection circuits improves the reliability under heavy load conditions.The TPL9032 series products provide SOT23-5,1×1 DFN-4,and 0.65×0.65 WLCSP-4 packages with guaranteed operating junction temperature range(TJ)from–40°C to+125°C.
