概述

Description

RT9169-33GVL is a fixed 3.3 V buck regulator from Richtek (RT9169 family). It is designed to generate a 3.3 V rail efficiently from a higher input voltage in compact, portable-power designs. Key features typically include an integrated switching MOSFET, enable/shutdown, soft-start, current-limit protection, and thermal shutdown, with the GVL suffix indicating a specific package variant. It suits battery-powered devices’ 3.3 V rails (MCU/SoC power, sensors, peripherals). For exact electrical specs (input range, switching frequency, max load current, quiescent current) and pinout, please refer to the official RT9169-33GVL datasheet.

Features

RT9169-33GVL is a fixed 3.3V LDO regulator from RichTek. Key features:
- Fixed 3.3V output
- Input range: 2.5V–5.5V
- Low dropout with high efficiency in low-voltage apps
- Low quiescent current (suitable for battery-powered designs)
- Enable pin for shutdown control
- Short-circuit/overcurrent protection
- Over‑temperature (thermal) shutdown protection
- Reverse current protection
- Package: SOT-23-5 (GVL), Pb-free/RoHS compliant
- Industrial temperature range (-40°C to 85°C)

Package

SOT-23-5 (5-pin) package.

Pinout

- Pin count: 5 pins (SOT-23-5 package)
- Function: Fixed 3.3V LDO regulator. Pins provide VIN, VOUT (3.3V), GND, EN (enable), and BYP (bypass) for improved noise/PSRR.

Manufacturer

- Manufacturer: Richtek Technology Corp. (Richtek)
- What kind of company: A Taiwanese fabless semiconductor company that designs and markets power-management ICs (PMICs), including DC-DC regulators, LDOs, battery charging, and related mixed-signal ICs.

Application
