Overview
Description
TPS78326DDCR is a fixed-output low-dropout regulator from TI’s TPS783 family. It delivers a stable 2.6 V output in a small DDCR package intended for portable and space-constrained applications.
Key points:
- Fixed output: 2.6 V
- Small, surface-mount package (DDCR suffix; check TI packaging details)
- Enable (EN) input to turn the regulator on/off
- Protective features: thermal shutdown and current-limit
- Low quiescent current suitable for battery-powered devices
Typical uses: power 2.6-V logic, microcontrollers, sensors, and other digital components in portable/embedded systems.
How to use: connect Vin to the input, GND to ground, Vout to the load, and drive EN high to enable. For exact electrical specs (input range, dropout, quiescent current, accuracy, current limit) and packaging details, consult the TPS78326DDCR datasheet and TI product page.
