概述

Description

TLV74233PDQNR is TI’s fixed 3.3 V low-dropout regulator (LDO) in the TLV742 family. It converts a higher input voltage to a stable 3.3 V supply with low dropout and low quiescent current, making it suitable for battery-powered and portable electronics. It includes protection features such as current limit and thermal shutdown (and often an enable option to switch the regulator on/off). The PDQNR suffix identifies the specific RoHS-compliant, surface-mount package and packaging options. Typical uses include powering microcontrollers, sensors, and other ICs in compact devices. You’ll need an appropriate output capacitor (ceramic) per the datasheet and to follow the recommended input range and thermal limits. For exact electrical specs, pinout, and recommended application conditions, consult the TI TLV74233 datasheet and product page.

Features

Here are the typical features of TLV74233PDQNR (fixed 3.3 V LDO):
- Fixed 3.3 V output
- Input voltage range: 1.8 V to 5.5 V
- Output current: up to about 150 mA
- Very low quiescent current; enable/shutdown control
- Enable pin for disabling the regulator
- Low dropout voltage (typical for light load; increases with load)
- Protection: overcurrent/short-circuit and thermal shutdown
- Stable with ceramic output capacitors (Cout ~2.2–10 µF) within specified ESR
- Small PDQ package, RoHS-compliant (PDQNR variant) suitable for compact layouts
Note: exact figures (current, dropout, ESR ranges, temperature range) should be verified from the datasheet for the specific operating conditions.

Package

SC-70-5 (also known as SOT-23-5) 5-pin package. NR indicates Tape-and-Reel.

Pinout

- Pin count: 5 pins
- Function: Fixed 3.3 V low-dropout regulator (LDO) with an enable input (in a 5-pin package, e.g., SOT-23-5).

Manufacturer

- Manufacturer: Texas Instruments (TI)
- What kind of company: A US-based multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

Application
