LP5912Q2.8DRVRQ1

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LP5912Q2.8DRVRQ1 is an automotive-grade low-dropout linear regulator from Texas Instruments, designed for high-performance power management in vehicle electronics. It delivers a fixed 2.8V output with a maximum load current of 500mA. The device operates within an input voltage range up to 6.5V and maintains regulation across a junction temperature range of -40°C to +125°C. Packaged in a compact 6-WSON (2x2) surface-mount footprint, it integrates essential control features including enable logic, soft-start functionality, and power-good indication.
