TPS76833QPWP

TPS76833QPWP is TI’s fixed 3.3 V low-dropout regulator (LDO) in the TPS768 family. It provides a stable 3.3 V rail from a higher input source with low quiescent current and simple enable control.
Key points:
- Fixed output: 3.3 V
- Low dropout and low quiescent current (suitable for battery-powered designs)
- Enable/shutdown control
- Protection features (short-circuit, thermal shutdown)
- Available in a compact QPWP package
Typical applications:
- Powering microcontrollers, sensors, and other digital ICs in portable or low-power devices
- Any system needing a clean 3.3 V supply from 1.8–6 V (check datasheet for exact input range)
How to use (brief):
- Connect VIN to the input with the recommended input capacitor
- Connect VOUT to the load with the recommended output capacitor (low ESR)
- Use EN to enable/disable
- Follow layout guidelines for caps placement and grounding
For exact electrical specs (max load current, dropout at load, input range, capacitor types), consult the TI TPS76833QPWP datasheet and product page.
