Overview

The TLV70033DCKT is a 200mA low-dropout (LDO) linear regulator that provides a fixed 3.3V output from an input up to 5.5V. It is designed for portable applications where board space is at a premium and a stable, low-noise supply is required for digital and analog circuits.

Why Choose This Part

This regulator features a very low dropout voltage of 0.25V at its full 200mA load, allowing for extended battery life as the source voltage drops. Its small SC-70-5 package and low quiescent current of 55uA make it ideal for compact, power-conscious designs.

Applications

Handheld Electronics
Provides a clean 3.3V rail for microcontrollers and sensors in battery-operated mobile devices.
Wireless Modules
Powers RF transceivers where a high PSRR of 68dB at 1kHz helps minimize supply noise interference.
Point-of-Load Regulation
Acts as a local regulator for noise-sensitive analog front-ends on dense PCB layouts.

Getting Started

To implement this part, place a 1uF ceramic capacitor close to the input and output pins for stability. Ensure the ground plane is adequate for heat dissipation, although thermal demands are minimal at low dropout voltages.
