TPL503133-S5TR

The TPL5031 series are 300mA high-PSRR, low-noise, low-dropout linear regulators with high output accuracy. This series supports a fixed output voltage range of 0.75V to 3.6V, as well as an adjustable output voltage range of 0.75V to 5V via an external resistor divider. The TPL5031 series operates stably with a 4.7μF or larger ceramic output capacitor. With a high PSRR of 70dB at 1kHz, the TPL5031 series is well-suited for applications sensitive to power supply ripple with high upstream noise, such as high-performance analog devices or high-definition imaging equipment. Output short-circuit protection and thermal overload protection circuits enhance reliability under heavy load conditions. The TPL5031 series is available in SOT23-5 and 1×1 DFN-4 packages, with a guaranteed operating junction temperature range of -40°C to +125°C.
