LTC1258CMS8-3#TRPBF - Precision Micropower, Low Dropout Voltage Reference

The LTC1258CMS8-3#TRPBF is a high-precision, low-power voltage reference part designed and manufactured by Linear Technology, a brand well-known for its high-performance analog integrated circuits. This specific model is tailored for applications where a stable and accurate reference voltage is crucial, and where power efficiency is of significant concern.

This voltage reference IC offers a fixed output voltage of 3.0 volts, providing a stable reference for ADCs, DACs, and other precision circuitry. It comes in a small MSOP-8 package, making it suitable for space-constrained applications without compromising on performance.

One of the key features of the LTC1258CMS8-3#TRPBF is its low dropout voltage, which ensures that it maintains a consistent output even with minimal input-to-output differential. This makes it an ideal choice for battery-powered and portable devices where the input voltage may vary or drop over time.

The device also boasts a low quiescent current, typically just 30µA, which contributes to its micropower designation. This low current draw helps to extend battery life in portable applications, making it an excellent choice for handheld devices, medical equipment, and other power-sensitive products.

Additionally, the LTC1258CMS8-3#TRPBF features high accuracy with an initial tolerance of ±0.6%, ensuring that the output voltage is precise and reliable over time, temperature, and varying input conditions. The temperature coefficient is specified at a low 50ppm/°C max, providing stable performance over a wide operating temperature range.

For protection and reliability, the device includes an over-temperature shutdown mechanism that safeguards the IC under abnormal thermal conditions. Its robust design allows it to operate effectively in industrial environments, with an operating temperature range from -40°C to +125°C.

In summary, the LTC1258CMS8-3#TRPBF from Linear Technology is a superior choice for designers who require a precise, low-power, and stable voltage reference in a compact form factor. Its low dropout voltage, micropower operation, and high accuracy make it a versatile component for a wide array of precision electronic applications.
