TPL5031 300mA Output, High PSRR, Low-Dropout Linear Regulato

　　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 4.7μF 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.
