Overview
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 0.75V to 3.6V and adjustable output voltage ranges from 0.75V to 5V with an external resistor divider. The TPL5031 series products are stable with a 4.7μF or larger ceramic output capacitor.
The TPL5031 series products have high PSRR with 70dB at 1kHz. 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.
