Overview

The TLV70033DDCR is a low-dropout (LDO) linear regulator from Texas Instruments designed for portable, battery-powered electronics. It provides a fixed 3.3V output at up to 200mA with a very low quiescent current of 31uA, making it ideal for maintaining efficiency in low-power standby modes. The device is housed in a compact SOT-23-5 Thin package and includes an active-high enable pin for power sequencing.

Why Choose This Part

This regulator features a high PSRR of 68dB at 1kHz, which effectively filters ripple from noisy switching power supplies. It includes integrated protection against overcurrent, overtemperature, and reverse polarity, ensuring robust operation in various environmental conditions. Its low noise floor of 48 nV/rtHz makes it suitable for sensitive analog and RF signal chains.

Applications

Battery-Powered Handhelds
Ideal for smartphones and PDAs where low quiescent current is critical for extending battery life.
Wireless Connectivity Modules
Provides clean, low-noise power for ZigBee and Bluetooth radios that require high PSRR.
WLAN PC Cards
Regulates power for PC add-on cards and peripheral modules with minimal board space requirements.
IoT Sensor Nodes
Supplies stable voltage to microcontrollers and sensors in distributed wireless networks.

Getting Started

To use this LDO, place a 1uF ceramic capacitor at both the input and output pins as close to the device as possible to ensure stability. The EN pin can be tied to the input voltage for always-on operation or driven by a GPIO for power management. Ensure the PCB thermal land is sufficient for the power dissipation expected from the voltage drop at 200mA.
