APPLICATIONS

Battery-Powered Instrumentation Portable Medical Instruments Data Acquisition Systems Industrial Process Control Systems Hard Disk Drives Automotive PIN CONFIGURATION 3-Lead SOT-23 (RT Suffix) ADR380/ ADR381 (Not to Scale) 3 VIN GND VOUT GENERAL DESCRIPTION The ADR380 and ADR381 are precision 2.048 V and 2.500 V band gap voltage references featuring high accuracy, high stabil- ity, and low-power consumption in a tiny footprint. Patented temperature drift curvature correction techniques minimize nonlinearity of the voltage change with temperature. The wide operating range and low power consumption make them ideal for 3 V to 5 V battery-powered applications. The ADR380 and ADR381 are micropower, low dropout voltage (LDV) devices that provide a stable output voltage from supplies as low as 300 mV above the output voltage. They are specified over the industrial (–40 °C to +85°C) temperature range. ADR380/ADR381 is available in the tiny 3-lead SOT-23 package. Table I.

REV. A–4– ADR380/ADR381 CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4,000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADR380/ADR381 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

REV. A ADR380/ADR381 –5– PARAMETER DEFINITIONS Temperature Coefficient The change of output voltage over the operating temperature change and normalized by the output voltage at 25 °C, expressed in ppm/°C. The equation follows: TCV ppm C VT VT VC T T O OO O / – –°[] = () () °() × () 25 10 where: VO (25°C) = VO at 25°C. VO (T1) = VO at Temperature 1. VO (T2) = VO at Temperature 2. Line Regulation The change in output voltage due to a specified change in input voltage. It includes the effects of self-heating. Line regulation is expressed in either percent per volt, parts-per-million per volt, or microvolts per volt change in input voltage. Load Regulation The change in output voltage due to a specified change in load current. It includes the effects of self-heating. Load regulation is expressed in either microvolts per milliampere, parts-per- million per milliampere, or ohms of dc output resistance. Long-Term Stability A typical shift in output voltage over 1,000 hours at a controlled temperature. The graphs TPC 24 and TPC 25 show a sample of parts measured at different intervals in a controlled environ- ment of 50°C for 1,000 hours. VV t – V t V ppm Vt– Vt Vt OO O O OO O = () () [] = () () 610 where: VO (t0) = VO at Time 0. VO (t1) = V O after 1,000 hours’ operation at a controlled temperature. Note that 50°C was chosen since most applications we have experienced run at a higher temperature than 25 °C. Thermal Hysteresis The change of output voltage after the device is cycled through temperature from +25°C to –40°C to +85°C and back to +25°C. This is a typical value from a sample of parts put through such a cycle. VV C V V ppm VC V VC O_HYS O O_TC O_HYS O O_TC O =° () [] = °() °() 25 106 where: VO (25°C) = VO at 25°C. VO_TC = VO at 25°C after temperature cycle at +25 °C to –40°C to +85°C and back to +25°C.
