Description

TLV70028DCKR is a fixed 2.8 V low-dropout (LDO) regulator from TI’s TLV700 family, in the DCKR packaging. It accepts input up to about 5.5 V and outputs a stable 2.8 V, with very low quiescent current—ideal for battery-powered, space‑constrained designs. Key features typically include ultra-low quiescent current, fast transient response, and built-in protection (current limit and thermal shutdown). Applications include microcontroller and sensor supplies, portable/wearable devices, and other handheld electronics. The DCKR suffix identifies the package variant; check the datasheet for exact pinout, layout recommendations, and full electrical specs (dropout, enable options if present, etc.).

Features

TLV70028DCKR features (concise):
- Fixed 2.8-V output
- Load current up to about 150 mA
- Ultra-low quiescent current
- Enable/shutdown input for power saving
- Low dropout voltage for efficiency
- Overcurrent protection and thermal shutdown
- Stable with ceramic output capacitors (Cout)
- Fast line and load transient response
- Small DCKR package (compact, RoHS-compliant)
Note: exact figures (Iq, dropout, ESR requirements) can vary by variant; consult the datasheet for precise operating specs.

Package

SC-70-5 (5‑pin) package, Tape & Reel.

Pinout

8 pins. It is a fixed 2.8 V low-dropout regulator (LDO) with an enable pin to turn the regulator on/off.

Manufacturer
