Description
TLV7041DCKR is a TI fixed-output low-dropout regulator (LDO) from the TLV7041 family. It’s designed for ultra-low quiescent current in battery-powered applications and provides a stable output with an enable (EN) control and protection features. The DCKR suffix denotes the specific packaging/lot RoHS-compliant variant (small, compact package such as SC-70/SOT-23-5 style).
Key points:
- Fixed output options (various voltages available per device)
- Low quiescent current and low dropout for efficient battery operation
- Enable input to turn the regulator on/off
- Protections: thermal shutdown and current limit for robustness
- Very small footprint suitable for microcontrollers, sensors, and other on-board analog/digital rails
For exact specs (Vout, Vin(max), Iout(max), Iq, dropout, EN threshold) refer to the TLV7041DCKR datasheet on TI’s website. If you tell me the needed output voltage or package, I can give more precise details.
