The TLE2425MDG4 is a dual ultra-low current 2.5V floating high-precision reference from Texas Instruments. This device is part of the company’s high-precision voltage reference and Power Management Integrated Circuit (PMIC) family. It offers a low-cost, on-chip solution for applications needing a wide operating temperature range and constant use.

The TLE2425MDG4 is designed specifically for applications requiring low current, accuracy and stability in a single-package device. It is suitable for 3V to 36V supply voltages and is available in a standard 8-pin SOIC package. The device offers high accuracy over the extended temperature range of -40°C to +85°C. It features independent dual outputs with low dropout of only 100mV and low-current capability of just 4.6mA.

The TLE2425MDG4 is optimized for operation over a wide range of supply voltages from 3V to 36V and is able to provide a constant voltage output of 2.5V regardless of external noise, environmental or temperature variations. The device is ideal for applications that require ultra-low current, stability and accuracy including instrumentation, laptop computers and consumer electronics.

The TLE2425MDG4 uses a classical 3-Terminal Voltage Reference to provide its accurate voltage output. This involves two terminals providing regulated power – the input (Vin) and the output (Vout). Between these two terminals is the reference voltage, which is determined using a precision resistive divider network in combination with a bandgap reference core. This provides a constant voltage regardless of the Vin or load conditions. The reference voltage is then further stabilized and regulated using a voltage loop with appropriate trim line compensation. This ensures against any thermal drift or variations in the resistive voltage divider.

The TLE2425MDG4 can also be used as a temperature compensating reference for current sources and amplifiers. A combined resistor and capacitance network connected to the device’s output can act as a temperature compensator, allowing the reference to better maintain a constant voltage output over a wider temperature range. It also improves the stability of the output voltage by reducing the effects of temperature on the resistive voltage divider.

The TLE2425MDG4 is an ideal choice for many applications due to its low-cost, low-current capabilities and high-precision over a wide temperature range. Its combination of features and accuracy makes it well suited for applications requiring precision voltage references and voltage regulation. It is categorized as a Voltage Reference PMIC device.
