## Description

Use this regulator to provide a reliable 3.3V for your projects. This genuine STMicroelectronics LDO is capable of providing up to 800mA which ought to be enough for most maker projects that operate at 3.3V.

If you're prototyping with this part, we have the perfect [SMT protoboard](https://core-electronics.com.au/makerverse-smt-protoboard.html) to help you get started.

Linear voltage regulators burn off excess power as **heat**, which means the device will get hotter for:

- higher currents
- greater differences between input and output voltage.
 
This product will be supplied as cut-tape or loose individual units.

**Features**

- Input Voltage: 4.5 - 15 (abs. max) V
- Output Voltage Fixed: 3.3V
- Dropout Voltage Vdo: 1.2V max
- Output Current: 800mA
- Package: SOT-223
