Product Overview: LT1129CS8

The LT1129CS8 is a high-performance, low dropout (LDO) voltage regulator from Linear Technology, designed to provide precision and stability in a wide range of power supply applications. This robust regulator offers a maximum output current of 700mA and is housed in a compact SO-8 package, making it an ideal choice for space-constrained applications.

Key Features

• Low Dropout Voltage: The LT1129CS8 features a low dropout voltage, typically 250mV at full load, which ensures efficient operation even when the input voltage is close to the output voltage. This low dropout characteristic makes it suitable for battery-powered devices where maximizing the usable battery life is crucial.
• Adjustable Output: With an output voltage range that can be set from 3.8V to 30V via external resistors, the LT1129CS8 offers great flexibility, catering to a broad spectrum of voltage requirements for various electronic components and systems.
• High Accuracy: The output voltage is guaranteed to be within ±2% tolerance, providing precise voltage regulation critical for sensitive electronic circuits.
• Thermal Protection: The device includes an internal thermal limiting circuitry that protects it from overheating. When the internal junction temperature exceeds the preset limit, the thermal protection circuitry reduces the output current to prevent damage.
• Low Quiescent Current: The LT1129CS8 features a quiescent current of only 5mA, which decreases to <1µA in shutdown mode, making it highly efficient for battery-powered applications.
