概述

Description

RT9193-15GB is a fixed-output low-dropout regulator (LDO) from RichTek. It provides a stable 1.5 V output and can supply up to about 150 mA. Key features typically include low quiescent current, short-circuit protection, and thermal shutdown. The “GB” suffix indicates a green (lead-free) package. It’s used to generate a 1.5 V rail for microcontrollers, sensors, and other low-power devices from a higher input source (up to around 5.5 V). For exact electrical specs (quiescent current, dropout at 150 mA, input range, accuracy), refer to the RT9193 datasheet.

Features

RT9193-15GB is a fixed-output LDO regulator. Key features:
- Fixed output: 1.5 V (RT9193-15GB)
- Output current: up to about 150 mA
- Low dropout suitable for battery-powered apps
- Enable pin for convenient shutdown
- Low quiescent current
- Protection: current limit, thermal/shutdown protection
- Stable with ceramic output capacitors (with appropriate ESR)
- Small package (SOT-23 family, RoHS/Green compliant)
Note: Always check the datasheet for exact pinout, capacitor requirements, and recommended operating conditions.

Package

RT9193-15GB comes in a SOT-23-5 (5-pin) package.

Pinout

- Pin count: 5 pins (SOT-23-5 package)
- Function: Fixed 1.5 V low-dropout regulator with an enable pin. Pins typically include VIN, VOUT, GND, EN (enable), and NC (not connected). EN enables/disables the regulator; VOUT provides 1.5 V when enabled and VIN is within the allowed range.

Manufacturer

Manufacturer: RichTek Technology Corporation (Richtek).
What kind of company: A Taiwanese fabless semiconductor company that designs power-management ICs (LDOs, DC-DC converters, battery chargers, etc.) and outsources fabrication to foundries.

Application
