概述

Description

LP5910-1.8DRVR is a fixed 1.8 V low-dropout regulator (LDO) with an enable control. It’s used to generate a stable 1.8 V rail for digital circuits from a higher input supply in compact, embedded designs.
Key points:
- Fixed output: 1.8 V
- Features: enable pin, short-circuit/overcurrent protection, thermal shutdown, low quiescent current
- Stability: requires input and output capacitors per datasheet (output capacitor ESR/voltage rating specified)
- Package/variant: DRVR suffix indicates a specific package/variant; check the datasheet for exact pins and footprint
- Applications: MCU/CPU cores, memory, FPGA I/O banks, portable devices, any 1.8 V rail
Basic hookup:
- VIN to input supply (above 1.8 V + dropout)
- VOUT to the 1.8 V rail
- GND to ground
- EN high to enable (or per datasheet)
- Place recommended capacitors close to pins
For exact electrical specs (max VIN, dropout, current limit, accuracy, temp range) and package details, consult the LP5910-1.8DRVR datasheet.

Features

LP5910-1.8DRVR features (concise):
- 1-channel constant-current LED driver for a single LED string
- Operates from the 1.8V logic/input domain (suitable for low-voltage apps)
- LED current set by an external resistor with stable regulation
- Enable/shutdown control
- PWM or DC dimming capability for brightness control
- Protection: open/short LED protection and overtemperature protection
- Low quiescent current for battery-powered devices
- Small 8-pin package (SOP-8/MSOP-8) suitable for compact layouts
Note: exact current range, protection thresholds, and dimming interface specifics are in the datasheet.

Package

LP5910-1.8DRVR’s package is vendor-specific; many datasheets list it in a small SMD package (often SOT-23‑5 or similar). Please specify the manufacturer or provide the datasheet for the exact package.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC-8/SOT-23-8)
- Function: LP5910-1.8DRVR is an LED driver IC that provides constant-current drive for LED strings; uses an external sense resistor to set current and includes enable/dimming inputs plus protection features.

Manufacturer

Manufacturer: Lapis Semiconductor Co., Ltd. It is a Japanese semiconductor company that designs and manufactures integrated circuits (ICs) and related semiconductor devices; it is now part of Renesas Electronics.
