The TPL8033 is a 20-V 200-mA high-performance lowdropout linear regulator with 1-μVRMS ultra-low noise and 110-dB ultra-high PSRR. The TPL8033 supports adjustable output from 1.2 V to 15 V with a single resistor and is stable with 4.7 μF to 100 μF. The TPL8033 implements a precision current reference and a high-performance voltage buffer. With an external capacitor connecting to the current reference, the output voltage noise can be further reduced. The TPL8033 features adjustable output current limit with a single external resistor and adjustable powergood threshold with an external resistors divider. The TPL8033 also integrates over-current protection and overtemperature protection to enhance system reliability. The TPL8033 provides thermal-enhanced 10-pin DFN3X3 and EMSOP packages with guaranteed operating temperature ranging from –40°C to +125°C.
