概述

Description

TPS72733DSER is TI’s fixed 3.3-V low-dropout (LDO) regulator in the DSER package. It delivers a stable 3.3-V output with very low quiescent current and low output noise, making it well-suited for battery-powered and noise-sensitive applications. Key features typically include an enable (EN) input for shutoff, thermal shutdown protection, and current limiting. The DSER suffix indicates a specific TI packaging option; check the datasheet for the exact package outline and pinout. Common uses are powering microcontrollers, sensors, and analog/digital front-ends where efficient, quiet regulation is important. How to use: provide Vin within the device’s input range, place the recommended input capacitor close to the regulator, connect EN to enable (or tie high for always-on operation), and place the recommended output capacitor with appropriate ESR per the datasheet. For precise electrical specs (input range, dropout, quiescent current, current limit, and package details), refer to the TPS72733DSER datasheet.

Features

TPS72733DSER Features:
- Fixed 3.3-V output LDO

- Low dropout voltage for efficient operation
- Enable input for easy on/off control
- Internal current limit and thermal shutdown for protection
- Short-circuit protection and robust reliability
- Tight line/load regulation and good output accuracy
- Small DSER package; RoHS-compliant

Package

SOT-23-5 (SC-70-5) package.

Pinout

- Pin count: 5 pins (SOT-23-5/DSER package)
- Function: TPS72733DSER is a fixed 3.3 V low-dropout regulator (LDO) with enable and bypass capability (IN, OUT, GND, EN, BYP).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is a US-based multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits and related electronics. It’s one of the world’s largest semiconductor producers.

Application

TPS72733DSER is a 3.3-V fixed low-dropout regulator with very low quiescent current and an enable pin. Ideal for battery-powered 3.3-V rails in portable devices, MCU/SoC power, sensors and data acquisition, wireless/RF modules, imaging/cameras, IoT wearables, and medical electronics needing low noise and fast transient response.

Equivalent

Equivalent 3.3V LDOs (≈150 mA) include: TLV1117-3.3, AMS1117-3.3, MIC5219-3.3, MCP1700-33, LP2985-3.3. Within TI, closest cross is TPS72733 (same family) or TPS7A33 (similar 3.3V LDO). Note pinout, footprint, dropout, and quiescent current vary—verify against your design.
