概要

Description

TPS7A0218PDBVR is a fixed-output low-dropout regulator from TI’s TPS7A02x family. It provides a clean 1.8-V supply with ultralow noise and high PSRR, making it suitable for sensitive RF/analog front-ends, ADCs/DACs, and microcontrollers. The PDBVR package houses the device with an enable (EN) control and protection features (overcurrent and thermal).
How to use (high level):
- Connect Vin to your input within the device’s specified range.
- Tie EN high to enable the regulator.
- Place recommended input and output capacitors close to the pins (output cap with the specified ESR).
- Follow layout guidelines for best noise and transient performance.
Applications include battery-powered or noise-sensitive systems requiring a stable 1.8-V rail. For exact electrical specs, pinout, capacitor values, and layout guidance, consult the TPS7A0218PDBVR datasheet and TI product page.

Features

Here are the key features of the TPS7A0218PDBVR:
- 1.8-V fixed-output low-dropout regulator (LDO)
- Ultra-low output noise with high PSRR
- Very low quiescent current (low power in both operation and shutdown)
- Low dropout voltage for operation near Vin
- Enable pin for shutdown/wake control
- Overcurrent/short-circuit protection and thermal shutdown
- Reverse-current protection to prevent backfeeding
- Robust ESD protection and wide operating temperature range
- Packaged in the PDBVR 8-pin package (robust, RoHS-compliant)

Package

DBV package.

Pinout

- Pin count: 5 pins (SOT-23-5, DBV package)
- Function: Fixed-output low-dropout regulator (LDO). Provides a regulated 1.8 V output from a higher input, with an enable (EN) control and a bypass (BYP) option for noise reduction. Pins are typically IN, GND, OUT, EN, and BYP.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: American multinational semiconductor company headquartered in Dallas, Texas, that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits (including power-management devices).

Application

Applications:
- Core/IO 1.8V rail for digital ICs (MCUs, DSPs, CPUs, FPGAs, memories)
- Biasing and reference rails for analog/RF front-ends and ADC/DACs
- Automotive ECUs and sensor modules needing low-noise 1.8V rails
- Battery-powered portable devices requiring low dropout and low quiescent current
- Pre-regulator/post-regulator in mixed-supply systems needing high PSRR
- Medical/industrial instrumentation demanding a stable, clean 1.8V supply

Equivalent

I can’t reliably give exact equivalents without your specs. Please share max output current, dropout, input range, tolerance, package, and any features (enable, PSRR). Generally, for a 1.8 V fixed-output LDO like TPS7A0218PDBVR, you can cross-reference TI’s TPS7A02x family and look at Analog Devices, Microchip, and On Semiconductor 1.8 V LDOs. Use the vendor cross-reference tools to get precise matches.
