TLV70028DCKR

TLV70028DCKR is a fixed-output, low-dropout regulator from TI’s TLV700 family. It provides a regulated 2.8 V rail from a single input supply (up to about 5.5 V), with ultra-low quiescent current for long battery life. Key features typically include fast startup, solid line/load regulation, and low output noise, plus protection like current limit and thermal shutdown. The DCKR suffix denotes the specific package/reel version for manufacturing. Common uses are powering microcontrollers, sensors, and other peripherals in portable or IoT devices that need a compact, efficient 2.8 V regulator. For exact electrical specs (max output current, dropout, quiescent current, and input range), consult the TLV70028DCKR datasheet.

Do you want direct cross-refs from other manufacturers or TI alternatives in different packages? If cross-refs, please share your target package, pinout, and max load current. Without that, I can’t ensure specs match TLV70028DCKR.

TLV70028DCKR features:
- Fixed output: 2.8 V
- Input range: 0.9 V to 5.5 V
- Output current: up to ~150 mA
- Ultra-low quiescent current: typical ~25 µA (normal operation)
- Low dropout: typically ~100–150 mV at moderate load
- Enable/shutdown input to turn regulator off
- Requires only a small output capacitor for stability (ceramic X5R/10 µF or similar per datasheet)
- Short-circuit protection and thermal shutdown
- Very small DCKR package (compact 5-pin device) suitable for space-constrained apps
Note: Refer to the TI datasheet for exact electrical specs, tolerance, and recommended capacitors.
