Descripción general

Description

TPS3306-18QDRQ1 is a Texas Instruments fixed-output buck (step-down) regulator. It takes a 2.7–5.5 V input and provides a stable 1.8 V output (the “-18” denotes 1.8 V). In the compact QDRQ1 package, it delivers up to roughly 600 mA with good efficiency for small, battery-powered systems. Key features typically include an enable input, soft-start to limit inrush, current-limit protection, thermal shutdown, and undervoltage lockout. It’s intended for generating core rails or other digital voltages in portable devices, microcontrollers, FPGAs, or memory subsystems. Like most fixed-output buck regulators, external components (inductor and supporting circuitry) are required per the datasheet. For exact pinout, electrical specs, efficiency, and application guidance, consult the TPS3306-18QDRQ1 datasheet.

Features

TPS3306-18QDRQ1 features (concise):
- Fixed 1.8 V reset threshold (voltage supervisor)
- Power-on reset and brown-out protection
- Very low quiescent current (typical ~1 µA)
- Open-drain /RESET output (requires pull-up)
- Manual reset input for external push-button
- Wide operating supply range: roughly 1.7 V to 5.5 V
- Small 6-pin QFN package (QDRQ1), RoHS-compliant
- Temperature range: -40°C to +125°C
- ESD protection on inputs/outputs
Note: Always refer to the latest datasheet for exact electrical specs and recommended application circuitry.

Package

It uses a 6‑pin VQFN package (2 mm × 3 mm).

Pinout

- Pin count: 8 pins (QFN-8 package, code QDRQ1)
- Function: 1.8-V voltage supervisor/reset generator. Monitors the 1.8-V rail and asserts a reset signal to the host MCU/system on power-up/power-down or brown-out events (reset output is active).

Manufacturer

Manufacturer: Texas Instruments Incorporated (TI).
What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and mixed-signal, digital, and embedded processing integrated circuits.

Application

TPS3306‑18QDRQ1 is a low‑quiescent‑current 1.8 V reset supervision device (POR/BOR). Applications include:
- Microcontroller and digital-logic reset with brown‑out protection
- Battery-powered portable devices (IoT nodes, wearables, sensors, data loggers)
- Systems needing reliable power‑on reset with fast response in a 1.8 V domain
- Any low‑power design requiring safe startup and reset integrity for 1.8 V logic.
