Overview

Description

RB751V40-QX is a fixed-output low-dropout (LDO) regulator from Ricoh’s RB751 family. It delivers a stable 4.0 V rail in a compact, RoHS-compliant package (QX suffix denotes a small-outline 5-pin/SC-70 style variant).
Key points
- Fixed 4.0 V output suitable for powering microcontrollers, sensors, and other logic
- Low quiescent current with good line and load regulation
- Protection features such as current limit and thermal shutdown
- Ideal for space-constrained, battery-powered or portable applications
Notes
- Exact electrical specs (input range, dropout, accuracy, current limit) vary by variant; consult the RB751V40-QX datasheet for precise numbers and recommended operating conditions.

Package

RB751V40-QX comes in a SOT-23-3 (SC-70 style) 3-pin package.

Pinout

Pin count: 3 pins.
Function: Voltage detector/reset supervisor (RB751V40) with a 4.0 V threshold, in a SOT-23/3-type package. (If another vendor uses the same part number, please provide the datasheet for exact pinout.)

Manufacturer

Manufacturer: Richtek Technology Corp.
What kind of company: A Taiwanese fabless semiconductor company that designs and sells power-management ICs (DC-DC converters, LDOs, PMICs) and related analog ICs for consumer electronics.

Application

RB751V40-QX is a fixed 4.0 V low-dropout regulator. Typical applications:
- Power supply for MCUs, memories and peripherals in portable devices
- Automotive and industrial electronics needing a stable 4V rail
- Sensors, GPS, RF and audio circuits requiring a clean, low-noise 4V supply
- Compact embedded designs where a small, reliable 4V regulation is needed
