概述

Description

TPS7A0233PDQNR is TI’s fixed-output, low-noise LDO regulator. It provides a clean 3.3-V output from a higher input, with ultralow output noise and high PSRR suitable for noise-sensitive analog/RF and microcontroller applications. The device includes protection features such as current limit, thermal shutdown, and reverse-current protection, making it robust for typical board conditions. It’s offered in the PDQNR package (a small DQFN-style package), which supports surface-mount designs and RoHS-compliant manufacturing.
Key points:
- Fixed 3.3-V output, low-noise, high PSRR
- Wide input range and good transient response (as per TPS7A0x family)
- Protection: current limit, thermal shutdown, reverse current
- Requires recommended input/output capacitors for stability
- Package: PDQNR (8-pin-ish DQFN style)
Ideal for precision analog, RF front-ends, sensor interfaces, and MCU supplies where a quiet 3.3-V rail is needed. For exact electrical specs, capacitor requirements, and pinout, consult the TI TPS7A0233 datasheet.

Features

Key features of TPS7A0233PDQNR (3.3 V fixed LDO in PDQNR):
- 3.3-V fixed-output low-noise LDO
- Ultra-low noise with high PSRR across frequency range
- Very low dropout for efficient operation
- Low quiescent current with enable pin for power saving
- Logic-level enable input to shut down/regulate on demand
- Overcurrent/short-circuit protection and thermal shutdown
- Wide input-voltage range and stability with a broad ESR output capacitor range
- Small 8-pin PDQ package for compact designs
Note: For exact electrical specs and recommended capacitors, refer to the datasheet.

Package

TPS7A0233PDQNR uses an 8-pin DQFN package (DQFN-8), typically 2×3 mm.

Pinout

- Pin count: 6 pins (PDQ package)
- Function: Fixed 3.3 V low-dropout regulator with enable input (EN). Provides VOUT from VIN with a GND reference; EN controls output on/off. The remaining pins are typically no-connect/test pins (NC).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- About the company: TI is an American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits, embedded processors, and other semiconductor products for global electronics markets.

Application

TPS7A0233PDQNR is a 3.3-V fixed-output, high-voltage-range low-noise LDO with enable and reverse-current protection. Typical applications: supply for microcontrollers, DSPs, and memories; analog front-ends, ADC/DACs, and sensor biasing; RF/communication modules; automotive and industrial electronics; portable/battery-powered devices needing low quiescent current and good PSRR; point-of-load regulation for regulators and op-amps in noise-sensitive circuits.
