Linear Technology LTC1258CMS8-5#PBF Low Dropout Reference
The LTC1258CMS8-5#PBF is a high-precision, low dropout voltage reference from Linear Technology, designed to ensure stability and accuracy in a wide range of applications. This product is a micropower, low dropout voltage reference that provides a fixed 5V output from an input voltage range of up to 12V with a typical supply current of just 45μA. This makes it an excellent choice for battery-powered equipment and other applications where power efficiency is critical.
Encased in an MSOP-8 package, the LTC1258CMS8-5#PBF is compact and suitable for space-constrained designs. It is characterized by a low temperature coefficient, typically 50ppm/°C, ensuring a consistent performance over a wide temperature range of -40°C to 85°C. This temperature stability, combined with a tight output voltage accuracy of ±0.2%, makes the LTC1258CMS8-5#PBF a reliable reference source for precision data converters, portable instrumentation, and industrial control systems.
The LTC1258CMS8-5#PBF also features a low dropout voltage, typically 400mV, which allows the reference to operate effectively even when the supply voltage is close to the output voltage. This low dropout capability is particularly beneficial in applications where the supply voltage may fluctuate or drop close to the output level, such as during battery discharge.
Moreover, the device includes a shutdown feature that reduces the supply current to less than 1μA, further enhancing its suitability for power-sensitive applications. When in shutdown mode, the reference output is turned off, allowing for additional power conservation.
Linear Technology's LTC1258CMS8-5#PBF is a robust and reliable solution for designers seeking a high-performance voltage reference. Its combination of low power consumption, high accuracy, and stability under varying conditions make it an ideal choice for a broad spectrum of applications, from portable devices to industrial systems.
