Description

TPS76918QDBVRQ1 is TI’s fixed-output 1.8-V low-dropout regulator (LDO) in the TPS769 family. It provides a stable 1.8-V rail with ultralow quiescent current, suitable for powering microcontrollers, sensors, and analog/RF blocks in portable and automotive applications. Key features typically include an enable (EN) pin to turn the regulator on/off and built‑in protections such as overcurrent and thermal shutdown. The QDBVRQ1 suffix denotes an automotive-grade (Q1) variant in a compact DBV package. For exact input range, maximum output current, dropout voltage, pinout, and thermal characteristics, consult the TPS76918QDBVRQ1 datasheet and packaging documentation.

Features

Key features of TPS76918QDBVRQ1:
- Fixed 1.8-V low-dropout regulator
- Automotive-grade (AEC-Q100 qualified), -40°C to 125°C
- Input voltage range up to 5.5 V (typical 2.7–5.5 V)
- Ultra-low quiescent current; enables via EN pin for shutdown
- Low dropout voltage suitable for battery-powered apps
- Low output noise and good line/load regulation
- Protections: current-limit protection and thermal/shutdown protection
- 100% production-tested; RoHS-compliant DBV package (industrial/automotive grade variant)
Note: Always refer to the datasheet for exact electrical specs and package details.

Package

The TPS76918QDBVRQ1 is supplied in a 5‑pin SOT‑23 package (TI package code DBV), a small 5‑lead surface‑mount package (~2.9 mm × 1.6 mm), automotive‑qualified (RQ1).

Pinout

- Pin count: 5 pins (DBV / SOT-23-5 package; part number includes Q for automotive qualification).
- Function: TPS76918QDBVRQ1 is a fixed 1.8 V low-dropout linear regulator (LDO) that provides a low‑noise, low‑quiescent‑current regulated output with an ENABLE pin and protection features (current limit/thermal shutdown). Typical pin functions are IN (input), OUT (regulated output), GND (ground), EN (enable), and a fifth pin that is NC/BYP/feedback-dependent on variant (consult the datasheet for exact pin map).

Manufacturer

Manufacturer: Texas Instruments (TI).
TI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal and embedded-processing integrated circuits, including power-management devices (like LDO regulators). It supplies components for automotive, industrial, consumer and communications markets and is headquartered in Dallas, Texas.

Application

- Portable and battery-powered devices (wearables, handhelds, IoT sensors)
- Microcontroller/SoC peripherals rails (1.8 V domain)
- RF/wireless modules and sensing front ends
- Space-constrained post-regulation and point-of-load applications
- Automotive/industrial designs (with automotive-grade Q1-qualified variant)

Equivalent

There is no guaranteed drop-in equivalent for TPS76918QDBVRQ1. For similar automotive‑qualified 1.8V, low‑noise LDOs check offerings from TI (TPS7A02‑Q1 family), Analog Devices (ADP17xx/ADP1720 series), ON Semiconductor (NCP4681‑Q1 variants) and Microchip (MCP18xx/MIC53xx families). Always verify pinout, package, dropout, noise, IQ, load current and AEC‑Q100 requirements before replacing.
