TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The LMx85-2.5 and LM385B-2.5 devices create a voltage reference for use in a variety of applications including amplifiers, power supplies, and current-sensing circuits. 8.2 Typical Application Figure 8 shows how to use these devices to establish a 2.5-V source from a 9-V battery. Figure 8. Reference From a 9-V Battery 8.2.1 Design Requirements The key design requirement when using this device as a voltage reference is to supply the LM385 with a minimum Cathode Current (IZ), as indicated in Electrical Characteristics. 8.2.2 Detailed Design Procedure To generate a constant and stable reference voltage, a current greater than IZ(MIN) must be sourced into the cathode of this device. This can be accomplished using a current regulating device such as LM334 or a simple resistor. For a resistor, its value should be equal to or greater than (Vsupply - Vreference) ÷ IZ(MIN) . 8.2.3 Application Curve Figure 9. Device Transient Response |
