In cases where there is no capacitance (CL), or the capacitance is small, or where a capacitor with an extremely low ESR value is used (e.g. ceramic), please use a capacitor (CL = 1.0µF [Tantalum]) in order to stop oscillation that may occur as the phase margin becomes smaller. 2. To reduce impedance between the power supply and the IC's input pin, which in turn will stop oscillation resulting from input voltage changes, connect a capacitor (CIN = more than 1.0µF, ESR low) to the input side of the IC. Further, operation may become unstable and oscillation may occur shoud impedance up to the IC's input be high (a state which could be brought about by several factors including which devices are added to the input side, the surrounding wiring and/or the input power supply.) Stability can be improved by regulating increases in input capacitance and by reducing impedance. 3. The regulator's input pin (VIN) and power supply pin are the same. Also, the voltage detector's power supply and the voltage regulator's power supply are the same. Therefore, to have the voltage detector operating normally, it is necessary to apply a voltage larger than the minimum operating voltage (1.5V) to the power supply input pin (VIN). 4. With CMOS output, the detector's output voltage equals the regulator's output voltage following release. Possible changes in the regulator's output voltage (VROUT), following regulator load changes, will be output at the detector's output pin (VDOUT). 5. As the operations of the detector will momentarily respond when steep rise and fall time voltages are input at the power supply pin (VIN), please ensure that the VIN(VDIN) pin's input frequency's rise and fall time is more than 5µ sec/V. 6. When using with the detector input pin (VDIN) connected to the regulator output pin (VOUT), the detector will momentarily respond as a result of transient output voltage changes brought about by the regulator's load changes. With large load currents and/or large load transitions from 1mA to 80mA for example, output voltage will momentarily drop, so please add a capacitor where CL=more than 4.7mF. 378 XC66D Series ■Operational Explanation GTiming Chart (N-ch open drain pull up voltage =Input voltage VIN) Regulator Input Voltage (VIN) Regulator Set-up Voltage (VOUT (T)) Min.

When a voltage greater than the release voltage (VDR) is applied to the voltage input pin (VIN, VDIN), input voltage (VIN, VDIN) will gradually fall. When a voltage greater than the detect voltage (VDF) is applied to the voltage input pin (VIN, VDIN), the output pin(VDOUT) voltage will be equal to the regulator's output voltage (VOUT). * With N-ch open drain configurations a state of high impedance means that should the pin be pulled up, voltage will be equal to pull up voltage. 2. When input voltage (VIN, VDIN) fall below detect voltage (VDF), output voltage (VDOUT) will be equal to ground level (VSS). 3. Should input voltage (VIN, VDIN) fall below the minimum operational voltage (VMIN), output will become unstable. Should VDIN fall below VMIN, voltage at the output pin (VDOUT) will be equal to ground level (VSS) . *With N-ch open drain configurations output will equal pull up voltage as the output pin is generally pulled up. 4. Should input voltage (VIN, VDIN) rise above ground voltage (VSS), output voltage (VDOUT) will equal ground level until the release voltage level (VDR) is reached. 5. The output pin voltage (VDOUT) will be equal to the regulator output voltage (VOUT) when input voltage (VIN, VDIN) rises above release voltage. *With N-ch open drain configurations it will be equal to the voltage dependent on pull up. Timing Chart B (VIN=voltages above set-up voltage + input/output voltage differential, VDIN = sweep voltage) Because a voltage higher than the minimum operating voltage is applied to the voltage input pin (VIN), ground voltage will be output at the output pin (VDOUT) during stage 3. (Stages 1, 2, 4, 5 are the same as in A above). Note : The difference between release voltage (VDR) and detect voltage (VDF) is the Hysteresis Range (6). 379 XC66D Series ■Test Circuits Circuit 1 Circuit 2 100kΩ VIN VIN （Tantalum） VDIN VOUT VDOUT VSS V VIN VIN VDIN VOUT VDOUT VSS A （Tantalum） 3 Circuit 3 Circuit 4 A VIN VIN VIN VDIN VOUT （Tantalum） VDOUT VSS （Tantalum） VSS VIN VDIN VOUT VDOUT 1µF （Tantalum） V A Circuit 5 Circuit 6 A VIN VDIN VOUT VDOUT VSS （Tantalum） VIN VIN VDIN VOUT VDOUT VSS A VIN 380 XC66D Series ■Typical Performance Characteristics (1) SUPPLY CURRENT vs. REGULATOR INPUT VOLTAGE XC66DN1922 5 VDIN＝Vss (2) SUPPLY CURRENT vs. DETECTOR INPUT VOLTAGE XC66DN1922 0.5 VIN＝10V (3) SUPPLY CURRENT vs. REGULATOR, DETECTOR INPUT VOLTAGE XC66DN1922 5 VIN＝VDIN Supply Current:Iss µA） （ Supply Current:Iss µA） （ 4 3 2 1 0 Ta＝80℃ 0.4 0.3 Ta＝80℃ 0.2 0.1 0 25℃ Supply Current:Iss µA） （ 4 3 2 1 0 0 1 2 3 Topr＝80℃ −30℃ −30℃ 25℃ 25℃ −30℃ 0 1 2 3 4 5 6 7 8 9 10 0 1 2 3 4 5 6 7 8 9 10 4 5 6 7 8 9 10 Regulator Input Voltage:VIN （V） Regulator Input Voltage:VDIN （V） Input Voltage:VIN , VDIN （V） 3 (4) DETECT VOLTAGE, RELEASE (5) DETECTOR OUTPUT VOLTAGE vs. VOLTAGE vs. AMBIENT TEMPERATURE DETECTOR INPUT VOLTAGE 2.2 2.1 VDR 2.0 1.9 1.8 1.7 −40 (6) DETECTOR N-ch DRIVER OUTPUT CURRENT vs. VDS XC66DN1922 12 VIN＝VDIN , VDS＝0.5V Detector Output Voltage:VDOUT V） （ Detect, Release Voltage:VDF, VDR （V） XC66DN1922 VIN＝VDIN XC66DN1922 3.0 2.5 2.0 1.5 1.0 0.5 0 0.0 0.5 Ta＝80℃ 25℃ VIN＝VDIN Detector N-ch Driver Output Current:IDOUT N-ch (mA) Ta＝−30℃ 10 8 6 4 2 0 0 0.5 1.0 1.5 2.0 2.5 80℃ 25℃ VDF −30℃ 1.0 1.5 2.0 2.5 3.0 −20 0 20 40 60 80 Ambient Temp.:Topr ℃） （ Detector Input Voltage:VDIN （V） Detector Input Voltage:VDIN （V） (7) DETECTOR N-ch DRIVER OUTPUT CURRENT vs. DETECTOR INPUT VOLTAGE XC66DN1922 1000 900 800 700 600 500 400 300 200 100 0 0 0.2 0.4 0.6 0.8 1.0 0.7V VIN＝0.8V Ta＝25℃ VIN＝VDIN XC66DN1922 10 Ta＝25℃ VIN＝VDIN Detector N-Ch Driver Output Current:IDOUT N-ch （mA） Detector N-ch Driver Output Current:IDOUT N-ch （mA） 8 6 VIN＝1.5V 4 2 0 0 0.3 0.6 0.9 1.2 1.5 VDS V） （ VDS V） （ (8) REGULATOR OUTPUT VOLTAGE vs. REGULATOR OUTPUT CURRENT XC66DN1922 Regulator Output Voltage:VOUT V） （ 2.4 （ Regulator Output Voltage:VOUT V） VIN＝3.2V （tantalum）, CL＝1µF （tantalum） CIN＝1µF XC66DN1922 2.5 2.0 VIN＝2.7V 1.5 1.0 0.5 0.0 3.2V Topr＝25℃ （tantalum）, CL＝1µF （tantalum） CIN＝1µF 3.6V Topr＝25℃ 4.2V 2.3 −30℃ 2.2 80℃ 2.1 Topr＝25℃ 2.0 0 10 20 30 40 50 60 0 100 200 300 400 Regulator Output Current:IOUT mA） （ Regulator Output Current:IOUT mA） （ 381 XC66D Series (9) REGULATOR OUTPUT VOLTAGE vs. REGULATOR INPUT VOLTAGE XC66DN1922 Regulator Output Voltage:VOUT V） （ 2.4 2.3 IOUT＝1mA 2.2 10mA 2.1 40mA 2 1.9 1.7 2.2 2.7 Regulator Output Voltage:VOUT V） （ Topr＝25℃ （tantalum）, CL＝1µF （tantalum） CIN＝1µF XC66DN1922 2.35 2.30 2.25 2.20 2.15 2.10 2 3 4 Topr＝25℃ （tantalum）, CL＝1µF （tantalum） CIN＝1µF IOUT＝1mA 40mA 10mA 3 5 6 7 8 9 10 Regulator Input Voltage:VIN （V） Regulator Input Voltage:VIN （V） (10) INPUT/OUTPUT VOLTAGE DIFFERENTIAL vs. REGULATOR OUTPUT CURRENT XC66DN1922 Input/Output Voltage Diff.:Vdif （V） 1.0 0.8 0.6 0.4 −30℃ 0.2 0.0 0 20 40 60 80 100 120 80℃ Topr＝25℃ VIN＝3.2V （tantalum）, CL＝1µF （tantalum） CIN＝1µF (11) REGULATOR OUTPUT VOLTAGE vs. AMBIENT TEMPERATURE XC66DN1922 Regulator Output Voltage:VOUT V） （ 2.30 VIN＝3.2V （tantalum）, CL＝1µF （tantalum） CIN＝1µF 2.25 IOUT＝10mA 2.20 40mA 2.15 2.10 −40 −20 0 20 40 60 80 Regulator Output Current:IOUT mA） （ Ambient Temp.:Topr ℃） （ (12) INPUT TRANSIENT RESPONSE 1 XC66DN1922 Regulator Output Voltage:VOUT V） （ Regulator Input Voltage:VIN （V） 6 4 2 0 −2 −4 −6 Output Voltage   Input Voltage XC66DN1922 Regulator Input Voltage:VIN （V） 6 5 4 3 2 1 0 6 4 2 0 −2 −4 −6 Output Voltage Input Voltage （tantalum） IOUT＝10mA , CL＝1µF （tantalum） IOUT＝1mA , CL＝1µF 6 5 4 3 2 1 0 Time （0.4msec/div） Time （0.4msec/div） 382 Regulator Output Voltage:VOUT V） （ XC66D Series (13) INPUT TRANSIENT RESPONSE 2 XC66DN1922 （ Regulator Output Voltage:VOUT V） Regulator Input Voltage:VIN （V） Regulator Input Voltage:VIN （V） 6 4 3 2 1 0 （tantalum） IOUT＝1mA , CL＝1µF XC66DN1922 4.0 3.5 3.0 2.5 2.0 1.5 6 4 3 2 1 0 4.0 3.5 3.0 2.5 2.0 1.5 Input Voltage Input Voltage Output Voltage Output Voltage Regulator Output Voltage:VOUT V） （ （tantalum） IOUT＝10mA , CL＝1µF Time （1msec/div） Time （1msec/div） 3 (14) LOAD TRANSIENT RESPONSE XC66DN1922 Regulator Output Voltage:VOUT V） （ (15) RIPPLE REJECTION RATE XC66DN1922 Ripple Rejection Rate:RR （dB） 200 160 120 80 VIN＝3.2VDC+1Vp−pAC （tantalum） IOUT＝10mA , CL＝1µF 4 3 2 1 Regulator Output Current:IOUT mA） （ （tantalum） VIN＝3.2V , CL＝1µF 60 50 40 30 20 10 0 0.01 Output Voltage Output Current 0 −1 40mA 1mA 0 40 0.1 1 10 Time （2msec/div） Ripple Frequency:f （kHz） 383
