概述

Description

TLV743285PDBVR is a fixed-output low-dropout regulator (LDO) from TI’s TLV743 family. It provides a regulated 2.85 V rail from a higher input voltage with features aimed at small, battery-powered electronics.
Key points:
- Fixed output: 2.85 V
- Low dropout and low quiescent current for efficiency
- Protection features: overcurrent/short-circuit protection and thermal shutdown
- Package: DBV (Pb-free) with Tape & Reel option
- Applications: microcontrollers, sensors, and compact portable devices needing a stable 2.85 V supply
For exact electrical specs (input range, dropout, max input, quiescent current, and pinout), consult the TI datasheet.

Features

TLV743285PDBVR is a fixed-output LDO from TI. Key features:
- Fixed output: 2.85 V
- Maximum output current: up to ~150 mA
- Input voltage range: about 2.7 V to 5.5 V
- Low dropout: suitable for battery-powered apps (dropout varies with load)
- Ultra-low quiescent current (typical tens of µA)
- Enable input (EN) to turn the regulator on/off
- Protection: short-circuit/overcurrent protection and thermal shutdown
- Low output noise and good line/load regulation
- Package: 5-pin SOT-23 (DBV) / PDBVR variant (RoHS-compliant)
Use cases: portable/battery-powered devices, microcontroller supplies, and other small VDD rails requiring a compact, low-quiescent 2.85 V regulator.

Package

DBV package (VSON-6), 6-pin. The trailing R indicates Tape & Reel.

Pinout

- Pin count: 5 pins (SOT‑23‑5/SC‑70‑5).
- Function: Fixed‑output low‑dropout (LDO) regulator with 2.85 V output; provides regulated VIN to VOUT with an EN pin to enable/disable; pins include VIN, VOUT, GND, EN, and a no‑connect/adjust pin depending on package.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational semiconductor company that designs and manufactures analog and digital integrated circuits, microcontrollers, and related products. It is one of the world's largest semiconductor companies, headquartered in Dallas, Texas.

Application

TLV743285PDBVR is a fixed 2.85-V low-dropout regulator in a small SOT-23-5 (DBV) package. It is suitable for battery-powered and portable electronics needing a compact, low-noise supply rail. Applications include powering microcontrollers, sensors (accelerometers, temperature sensors), analog front-ends, ADC/DAC references, RF/wireless modules, wearables, medical devices, and other embedded systems requiring a stable 2.85-V rail.

Equivalent

TLV743285PDBVR is TI’s 2.85-V fixed-output LDO (SOT-23-5). There isn’t a direct one-to-one cross-reference across vendors. Closest substitutes are 2.8–2.9 V fixed LDOs from other vendors with similar current, dropout, and quiescent current. For precise equivalents, please provide: input voltage range, max output current, dropout, package, and tolerance. I can then give exact cross-reference part numbers.
