The R1141Q261B-TR is a voltage regulator IC manufactured by Ricoh. It is a low-dropout (LDO) regulator, meaning it can maintain a stable output voltage even when the input voltage is only slightly higher than the desired output. This makes it suitable for battery-powered devices and other applications where the input voltage may vary.

Applications

• Battery-powered devices: Smartphones, tablets, wearables.
• Portable equipment: Digital cameras, MP3 players, handheld gaming consoles.
• Power management circuits: Used to regulate voltage for sensitive components like microcontrollers and sensors.
• Wireless communication devices: Bluetooth modules, Wi-Fi modules.

Features

• Low dropout voltage: Ensures stable output even with low input voltage.
• High output voltage accuracy: Provides a precise and reliable voltage supply.
• Low quiescent current: Minimizes power consumption when the regulator is not actively supplying current.
• Overcurrent protection: Protects the regulator and connected devices from damage due to excessive current.
• Thermal shutdown protection: Prevents the regulator from overheating and failing.
• Small package: Allows for compact designs.
