1 9-; Rev 2; 6/97, Low-Dropout, General Description The / precision 2. and 4.96 micropower voltage references consume a maximum of only and operate from supply voltages up to. The combination of ultra-low quiescent current and low dropout makes them ideal for battery-powered equipment. They source and sink up to with only input voltage headroom, which makes the 2. ideal for use with a 3 supply and the 4.96 ideal for use with a supply. Initial accuracy of.2% at +2 C (± for the, ±8 for the ) and low 4ppm/ C max drift make these references suitable for a wide range of precision applications.

Generates an output voltage proportional to junction temperature. Ground Trim. Connect to the center of a voltage divider for output trimming. Otherwise make no connection. Reference Output Compensation Input. Connect C LOAD / capacitor from to COMP to provide capacitive load compensation. Applications Information Trimming the The / s output voltage is trimmed for.2% tolerance at +2 C. If additional OUT trimming is desired, connect a potentiometer to, as shown in Figures a and b. Adjusting OUT away from its factory-trimmed voltage typically changes the output voltage tempco by 7ppm/ C per. Reducing Input Ripple with an Input Filter The Power-Supply Rejection Ratio vs. Frequency graph in the Typical Operating Characteristics shows ripple rejection between Hz and 2kHz. As input RC filter with a pole less than Hz, as shown in Figure 2, further attenuates input ripple with this band. The voltage drop across the input resistor (due to supply and load current) slightly increases the dropout voltage. The increase is given by [(ILOAD + ISUPPLY) R]. Choosing the Output and Compensation Capacitors Connecting a capacitor between oid and reduces load transients. If the load exceeds 3, connect a minimum of pf from OUT to. The type of capacitor is not critical. If the total load capacitance from OUT to (CLOAD = output capacitor + other capacitive load) is larger than pf, connect a compensation capacitor with a value of CLOAD/ between COMP and OUT. 3 IN M.M RANGE: -3/+8 Figure a.

Input Filter Reduces Input Ripple TEMP Output The TEMP output provides a voltage proportional to the / junction temperature. Since the power dissipation of the / is <µw typ, the junction temperature is within. C of the ambient temperature. Although it goes unused in most applications, the ambient temperature information given by the TEMP output may be used to control LCD contrast, or to provide ADC gain compensation or thermal out-of-range indication. TEMP must be buffered or connected to a high-impedance input. Operating Temperature Window Comparator In Figure 3, a window comparator monitors the TEMP output and indicates if the temperature is out of the nominal operating range. For the resistor values shown, the circuit will indicate an out-of-range condition if the ambient temperature should rise above +8 C or dip below -4 C. Start-Up When the input voltage is below the factory-selected output voltage, the / can draw excessive supply current (hundreds of microamps). If the source resistance is too high, the voltage drop across the source resistance can prevent the input voltage to the device from reaching the minimum dropout voltage. Therefore, when using the / in lowdropout applications, ensure that the power supply has a low source resistance. Figure 3.
