Figure 21 shows a simplified block diagram of extremely low dropout voltage. With the exception of the REF50xx. the REF5020, which has a minimum supply requirement of 2.7V, these references can be operated with a supply of 200mV above the output voltage in an unloaded condition. For loaded conditions, a typical dropout voltage versus load plot is shown in Figure 6 of the Typical Characteristics. The REF50xx provides a very accurate voltage output. However, VOUT can be adjusted from the nominal value for the purpose of trimming system errors by configuring the TRIM pin (pin 5). The TRIM pin provides for adjustment of the voltage at VOUT over a ±15mV range. Figure 23 shows a typical circuit using the TRIM pin to adjust VOUT. When using this technique, the temperature coefficients of the resistors can degrade the temperature drift at the output. Figure 21. REF50xx Simplified Block Diagram Figure 22 shows the typical connections for the REF50xx. A supply bypass capacitor ranging between 1 μF to 10μF is recommended. A 1μF to 50 μF, low-ESR output capacitor (CL) must be connected to VOUT. Figure 23. VOUT Adjustment Using the TRIM Pin The REF50xx is designed for minimal drift error, which is defined as the change in output voltage over temperature. The drift is calculated using the box method, as described by the following equation: Figure 22. Basic Connections The REF50xx features a maximum drift coefficient of 3ppm/ °C for the high-grade version, and 8ppm/°C for the standard-grade. 9 Copyright © 2007, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): REF5020 REF5025 REF5030 REF5040 REF5045 REF5050 |
