Description
Introduction to TPS70618DBVR
- TPS70618DBVR is a fixed-output low-dropout regulator (LDO) from TI, delivering a stable 1.8 V rail for portable electronics.
- It targets low quiescent current, good line/load regulation, and ease of use in compact designs.
- Features include an enable (EN) input to power down the regulator for efficiency.
- Package: DBVR (small, surface-mount) suitable for tight PCB layouts.
- Typical applications: MCU cores, sensors, analog/digital subsystems that require a clean 1.8 V supply.
- For exact electricals (input range, max output current, dropout, accuracy, protections), refer to the datasheet.
- To use: connect IN to a higher supply within spec, GND to system ground, and EN to a logic signal (or tied high to enable). Add the recommended input/output capacitors near the regulator per datasheet guidelines.
Note: Specs vary by device revision; always consult the datasheet for precise numbers and protection features.
