Fixed 3.3V Linear Voltage Regulator. Low dropout, 500mA output, and internal protection. Perfect for battery-powered DIY electronics and microcontrollers such as ESP32, STM32, and related sensor breakout boards.
Description
The TLV2217-33 is an essential component for any maker working with 3.3V electronics, such as ESP32, STM32, or modern sensors. Unlike standard regulators that require a much higher input voltage to function, this "Low Dropout" (LDO) version can provide a rock-solid 3.3V output even when the input voltage is only slightly higher. It is designed to handle up to 500mA of current, making it powerful enough for Wi-Fi modules and small motor controllers. It also features built-in safety mechanisms like thermal shutdown and current limiting to protect your project from accidental damage.
Features
Fixed 3.3V Output: No external resistors needed to set the voltage.
Low Dropout Voltage: Operates efficiently even when the battery voltage drops close to 3.3V.
500mA Output Current: Provides plenty of power for most microcontroller projects.
Built-in Protection: Includes over-temperature shutdown and current limiting to prevent burnout.
High Accuracy: Maintains a precise output voltage with minimal drift.
Compact Design: Available in small packages (like SOT-223 or TO-220) that fit easily into breadboards or custom PCBs.
Applications
Battery Powered Devices: Extends battery life by operating at low voltage thresholds.
Microcontroller Power: Ideal for powering 3.3V boards like ESP8266, ESP32, and Arduino Pro Mini.
Sensor Hubs: Provides clean, noise-free power for sensitive analog and digital sensors.
Portable Electronics: Used in hand-held gadgets and DIY wearables.
Voltage Regulation: Dropping 5V USB power down to a safe 3.3V level.
