概要
Description
TLV743285PDBVR is a fixed-output, low-dropout regulator from TI’s TLV743 family. It provides a regulated 2.85 V output from a single-supply input (typically up to about 5.5 V) and can deliver roughly 150–200 mA depending on conditions. It includes an enable (EN) pin to shut the device down for ultra-low standby current. Protection features usually include current limiting and thermal shutdown. The PDBVR suffix indicatesPb-free packaging in TI’s DBV package with reel/tape options.
Typical application: compact electronics needing a small, efficient 2.85 V supply for MCUs, sensors, radios, etc.
How to use: connect VIN to your supply, GND to ground, VOUT to the load with the recommended input/output capacitors per datasheet. Tie EN high to enable (or drive from a control signal); pull EN low to disable. For exact specs (min Vin at full load, dropout, capacitors ESR, max current), consult the TLV743285PDBVR datasheet.
