PMIC - Voltage Reference

The LM185H-2.5 is a low-dropout voltage reference IC (Integrated Circuit) that is manufactured by Texas Instruments. It belongs to the family of LR (Lowdropout) voltage regulators with ultra-low dropout voltage. The characteristics of this device make it suitable for a wide range of applications that require a LT (Low Temperature) drift voltage reference.The LM185H-2.5 is a two-terminal voltage reference with a nominal voltage of 2.5V. It has very low output voltage drift due to its TT (TemperatureTracker) technology. This technology allows the circuit to automatically adjust the output voltage according to temperature variations. This gives better performance over wide operating temperature range and makes this IC suitable for use in extreme temperature conditions.The output voltage of the LM185H-2.5 is relatively stable, with a maximum temperature coefficient of 0.2mV/°C. This ensures that the circuit has excellent long-term stability and can withstand all environmental conditions and operate reliably over a wide temperature range. The device is available in surface mount package (TQFP, DFN, MSOP etc.) and also comes in TO-3 package.The typical application of LM185H-2.5 is in portable electronics, office equipment, automotive, and other consumer electronics. Some of these applicationsinclude voltage reference, voltage clamp and overvoltage protection in electronic spikeshields, battery charger, etc.When it comes to operation, the LM185H-2.5 employs a bandgap reference circuit to create a voltage reference voltage that is relatively insensitive to temperature variations and load conditions. This provides very stable and precise voltage reference.The basic principle of the LM185H-2.5 is to create a "constant voltage" that remains unaffected even if the current demand or supply circuit changes. The reference voltage for the device is typically 2.5V and its output voltage is adjustable in a range from 2.18V to 2.95V. The device has excellent current handling capabilities and can deliver up to 5A of current with an output impedance of 7.5 mΩ at full load current of 5A.The LM185H-2.5 is a very reliable and easy to use device and provides a wide range of features such as low voltage dropout, low output resistance, low temperature coefficient, low noise and high accuracy voltage reference. This makes it ideal for applications that require a very precise and stable voltage reference in a wide range of temperature conditions. Therefore, the LM185H-2.5 is suitable for a wide range of applications in the consumer, automotive and industrial markets.
