TPS70618DBVR

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.

Direct drop-in equivalents for TPS70618DBVR (1.8V fixed LDO, ~150 mA) are TI variants of the TPS70618 in other packages. For non-TI cross-refs with similar specs, consider ST LP5907-1.8, Analog Devices ADP170AUJ-1.8, and Microchip MCP1700-1.8 (verify footprint and pinout).

TPS70618DBVR features (highlights):
- Fixed 1.8 V output
- Input voltage range up to 5.5 V
- Ultra-low quiescent current (microamp range)
- Low dropout voltage for efficient operation
- Enable pin for shutdown/power-down
- Short-circuit/current-limit protection and thermal shutdown
