NIC = NO INTERNAL CONNECT. 02 74 7- 00 2 Figure 2. 8-Lead, SOIC Surface-Mount Package GENERAL DESCRIPTION The ADR01, ADR02, ADR03, and ADR06 are precision 10.0 V, 5.0 V, 2.5 V, and 3.0 V band gap voltage references featuring high accuracy, high stability, and low power consumption. The parts are housed in tiny, 5-lead SC70 and TSOT packages, as well as in 8-lead SOIC versions. The SOIC versions of the ADR01, ADR02, and ADR03 are drop-in replacements1 to the industry- standard REF01, REF02, and REF03. The small footprint and wide operating range make the ADR0x references ideally suited for general-purpose and space-constrained applications. With an external buffer and a simple resistor network, the TEMP terminal can be used for temperature sensing and approximation. A TRIM terminal is provided on the devices for fine adjustment of the output voltage. The ADR01, ADR02, ADR03, and ADR06 are compact, low drift voltage references that provide an extremely stable output voltage from a wide supply voltage range. They are available in 5-lead SC70 and TSOT packages, and 8-lead SOIC packages with A, B, and C grade selections. All parts are specified over the extended industrial (–40°C to +125°C) temperature range. The ADR01, ADR02, ADR03, and ADR06 A grade in 8-lead SOIC are qualified for automotive applications. Table 1. Selection Guide Part Number Output Voltage ADR01 10.0 V ADR02 5.0 V ADR03 2.5 V ADR06 3.0 V 1 ADR01, ADR02, and ADR03 are component-level compatible with REF01, REF02, and REF03, respectively. No guarantees for system-level compatibility are implied. SOIC versions of ADR01/ADR02/ADR03 are pin-to-pin compatible with 8-lead SOIC versions of REF01/REF02/REF03, respectively, with the additional temperature monitoring function.

Data Sheet ADR01/ADR02/ADR03/ADR06 Rev. R | Page 9 of 20 TERMINOLOGY Dropout Voltage (VDO) Dropout voltage, sometimes referred to as supply voltage head- room or supply output voltage differential, is defined as the minimum voltage differential between the input and output necessary for the device to operate, such as VDO = (VIN – VOUT)min|IL = Constant Because the dropout voltage depends upon the current passing through the device, it is always specified for a given load current. Temperature Coefficient (TCVO) The temperature coefficient relates the change in output voltage to the change in ambient temperature of the device, as normalized by the output voltage at 25°C. This parameter is expressed in ppm/°C and can be determined by the following equation: ( ) [ ]Cppm/10)25( )()( 6 12 12   × −× − = TTCV TVTV TCV OUT OUTOUT O where: VOUT(25°C) is the output voltage at 25°C. VOUT(T1) is the output voltage at Temperature 1. VOUT(T2) is the output voltage at Temperature 2. Output Voltage Hysteresis (ΔVOUT_HYS) Output voltage hysteresis represents the change in output voltage after the device is exposed to a specified temperature cycle. This may be expressed as either a shift in voltage or a difference in parts per million from the nominal output as follows: VOUT_HYS = VOUT(25°C) – VOUT_TC [V] ]ppm[10 )25( )25( 6_ _ × − = CV VCV V OUT TCOUTOUT HYSOUT   where: VOUT(25°C) is the output voltage at 25°C. VOUT_TC is the output voltage after temperature cycling. Thermal hysteresis occurs as a result of forces exhibited upon the internal die by its packaging. The effect is more pronounced in parts with smaller packages. Long-Term Stability (ΔVOUT_LTD) Long-term stability refers to the shift in output voltage at 25°C after 1000 hours of operation in a 25°C environment. This may also be expressed as either a shift in voltage or a difference in parts per million from the nominal output as follows: ΔVOUT_LTD = |VOUT(t1) – VOUT(t0)| [V] ]ppm[10 )( )()( Δ 6 0 01 _ × − = tV tVtV V OUT OUTOUT LTDOUT where, VOUT(t0) is the VOUT at 25°C at Time 0. VOUT(t1) is the VOUT at 25°C after 1000 hours of operation at 25°C. Line Regulation Line regulation refers to the change in output voltage in response to a given change in input voltage, and is expressed in either percent per volt, parts per million per volt, or microvolt per volt change in input voltage. This parameter accounts for the effects of self-heating. Load Regulation Load regulation refers to the change in output voltage in response to a given change in load current, and is expressed in either microvolts per milliampere, parts per million per milliampere, or ohms of dc output resistance. This parameter accounts for the effects of self-heating.
