Présentation
Description
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.
Features
- Fixed output: 2.6 V
- Input voltage range: 1.8 V to 5.5 V
- Output current: up to ~150 mA
- Very low quiescent current (typical ~50 µA) with enable
- Low dropout: ~120–180 mV at 150 mA (typical)
- Enable pin for shutdown (low-power operation)
- Overcurrent protection and thermal shutdown
- Stable with small ceramic capacitors (low ESR; typically 1 µF or larger)
- Packaging: 8-pin DDCR (compact LDO package)
Note: Specifications can vary by exact device revision; always check the latest TI datasheet for exact numbers.
Pinout
- Function: Fixed-output low-dropout regulator (TPS78326) with a 2.6 V output and an enable pin; provides regulation from a higher input voltage to 2.6 V. Includes typical input, output, ground, and enable pins.
Manufacturer
- What kind of company: An American multinational technology company that designs and manufactures semiconductors and integrated circuits, with a focus on analog, mixed-signal, and embedded processing products.
Application
- Battery-powered portable devices needing a 2.6 V rail
- Microcontrollers, DSPs, and other digital ICs
- Sensor front-ends (MEMS, ADC/DAC) and analog blocks
- RF/wireless modules and transceivers
- Portable medical devices and IoT/wearables
- Any system requiring a low-quiescent, stable 2.6 V supply with good line/load regulation
