TPL903233-DF1R

300-mA high PSRR, ultra-low noise, and low dropout linear regulators with high output accuracy. Support both fixed output voltage ranges from 0.9 V to 5 V and are stable with 1 μF or larger ceramic output capacitor. Have high PSRR with 87.9 dB at 10 kHz and 8.6 μVRMS ultra-low noise. 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 improve the reliability under heavy load conditions. Provide SOT23-5, DFN1x1-4, and WLCSP0.65x0.65-4 packages with guaranteed operating junction temperature range (TJ) from -40°C to +125°C.
