Description

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 an adjustable output current

limit with a single external resistor and adjustable

power-good threshold with an external resistor divider.

The TPL8033 also integrates over-current 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
