The TPL5031 series products are 300-mA high PSRR, low noise, and low dropout linear regulators with high output accuracy. The TPL5031 series products support both fixed output voltage ranges from 0.75 V to 3.6 V and adjustable output voltage ranges from 0.75 V to 5 V with an external resistor divider. The TPL5031 series products are stable with a 4.7 μF or larger ceramic output capacitor. The TPL5031 series products have high PSRR with 70 dB at 1 kHz. This feature makes TPL5031 series products very suitable for power-ripple-sensitive applications with high noise from the 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. The TPL5031 series products provide SOT23-5 and 1×1 DFN-4 packages with a guaranteed operating junction temperature range from −40°C to +125°C.
