概述

Description

TPS76618DR is a fixed 1.8V low-dropout regulator (LDO) from TI’s TPS766 family. It converts a higher input voltage within its rated range to a stable 1.8V output, suitable for battery-powered microcontrollers, sensors, and other 1.8V subsystems. Key features typically include an enable input for power-down, overcurrent protection, and thermal shutdown, along with good transient response. Output stability requires a suitable capacitor (and ESR as specified in the datasheet) at the output. The DR suffix denotes a specific packaging/tape-and-reel option. For exact specs—input range, dropout, max load current, quiescent current, PSRR—and recommended layout, consult the TPS76618DR datasheet and TI product page.

Features

TPS76618DR is a 1.8 V fixed-output low-dropout regulator from TI. Key features include:
- Fixed 1.8 V output
- Input voltage range up to 5.5 V
- Very low quiescent current (ultra-low power in sleep/idle)
- Low dropout for efficient operation
- Enable pin to turn the regulator on/off
- Protective functions: current limit and thermal shutdown
- Good line/load regulation for stable output
- Suitable for portable/battery-powered designs
- Available in compact packaging (DR suffix indicates a specific TI package)
Note: for exact electrical specs (quiescent current numbers, dropout voltage, current limit, and package details), please refer to the TI datasheet for TPS76618DR.

Package

TPS76618DR comes in an 8-pin VSSOP (Very Small Outline Package).

Pinout

- Pin count: 8 pins (VSSOP-8 package)
- Function: Fixed-output low-dropout regulator (LDO) that regulates VIN to VOUT = 1.8 V, with an enable (EN) input to enable/disable the regulator.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational technology company that designs and manufactures semiconductors and integrated circuits, specializing in analog, mixed-signal, and embedded processing solutions.

Application

Applications for TPS76618DR (1.8 V fixed LDO) include:
- 1.8-V core/I/O rails for MCUs, DSPs, FPGAs, and ASSPs
- Local regulation for sensors, ADC/DACs, and memory
- Power management in portable/battery-powered devices (wearables, handhelds)
- Embedded systems and consumer electronics needing a small, low-quiescent, low-noise 1.8-V rail
- Data acquisition, instrumentation, and networking equipment requiring a stable 1.8-V supply

Equivalent

TPS76618DR is a 1.8 V fixed-output LDO from TI (~150 mA). Direct drop-in equivalents depend on package/pinout, but closest alternatives include:
- TI TLV70018 (1.8 V LDO)
- Microchip/Microsemi MIC5219-1.8 (1.8 V)
- Torex XC6206P182MR (1.8 V)
- ON Semiconductor NCP4681-1.8 (1.8 V)
- Analog Devices ADP151AYM-1.8 (1.8 V)
