It is available in DFN 1x1-4L and SOT23-5L packages, allowing the maximum space saving. The device is stabilized with a ceramic capacitor on the output. The ultra low drop voltage, low quiescent current and low noise features, together with the internal soft-start circuit, make the LD39020 suitable for low power batteryoperated applications. An enable logic control function puts the LD39020 in shutdown mode allowing a total current consumption lower than 0.1 µA. Constant current and thermal protection are provided.

By increasing the startup time up to 100µs, without the need of any external soft start capacitor, this feature is able to keep the regulator inrush current at startup under control. 6.2 Output discharge function The LD39020 integrates a MOSFET connected between Vout and GND. This transistor is activated when the EN pin goes to low logic level and has the function to quickly discharge the output capacitor when the device is disabled by the user. The device is available with or without auto-discharge feature. See Table 10: "DFN1x1-4L order codes" for more details. 6.3 Input and output capacitors The LD39020 requires external capacitors to assure the regulator control loop stability. Any good quality ceramic capacitor can be used but, the X5R and the X7R are suggested since they guarantee a very stable combination of capacitance and ESR overtemperature. Locating the input/output capacitors as closer as possible to the relative pins is recommended. The LD39020 requires an input capacitor with a minimum value of 1 μF. This capacitor must be located as closer as possible to the input pin of the device and returned to a clean analog ground. The control loop of the LD39020 is designed to work with an output ceramic capacitor. This capacitor must meet the requirements of minimum capacitance and equivalent series resistance (ESR), as shown in Fig17. To assure stability, the output capacitor must maintain its ESR and capacitance in the stable region, over the full operating temperature range. The LD39020 shows stability with a minimum effective output capacitance of 220 nF. However, to keep stability in all operating conditions (temperature, input voltage and load variations), a minimum output capacitor of 0.47 µF is recommended. The suggested combination of 1 μF input and output capacitors offers a good compromise among the stability of the regulator, optimum transient response and total PCB area occupation. 12/30 DocID025316 Rev 3 LD39020 Typical characteristics (CIN = COUT = 1 µF, VEN to VIN, TJ = 25°C unless otherwise specified) Figure 4: Output voltage vs. temperature (IOUT = 1 mA) Figure 5: Output voltage vs. temperature (IOUT = 200 mA) Figure 6: Line regulation vs. temperature Figure 7: Load regulation vs. temperature Load regulation 7 Typical characteristics DocID025316 Rev 3 13/30 Typical characteristics LD39020 Figure 8: Quiescent current vs. temperature (IOUT = 0 mA) Figure 9: Quiescent current vs. temperature (IOUT = 200 mA) Figure 10: Shutdown current vs. temperature Figure 11: Quiescent current vs. load current 1 0.9 Quiescent current [µA] 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 -40 -25 0 25 55 85 125 Temperature [°C] V IN=4.3V, V EN=G N D AM13861V1 Figure 12: Quiescent current vs. input voltage Figure 13: Dropout voltage vs. temperature 275 250 Dropou t Voltage [mV] 225 Io ut = 30 m A 200 Io ut = 50 m A 175 Io ut = 10 0 mA Io ut = 20 0 mA 150 125 100 75 50 25 0 -40 -25 0 25 55 85 125 Temperature [°C] AM13864V1 14/30 DocID025316 Rev 3 LD39020 Typical characteristics Figure 14: Supply voltage rejection vs. frequency Figure 15: Supply voltage rejection vs. input voltage 100 Io ut = 1mA 90 Io ut = 30 m A Io ut = 10 0 mA 80 Io ut = 20 0 mA SVR [dB] 70 60 50 40 30 20 10 0 100 1000 10000 100000 1000000 Frequency [Hz] VIN=2V +/- 200mV, VOUT= 1V, COUT =1µF AM13865V1 Figure 16: Output noise spectral density Figure 17: Stability area vs. (COUT, ESR) Figure 18: Enable startup (VOUT = 1 V) Figure 19: Enable startup (VOUT = 5 V) V EN V EN V OUT V OUT IOUT IOUT V IN =2V, V EN =0V to V IN, I OUT=0.2 A , V OUT=1 V, T r =5µ s V IN=5.5 V, V EN=0V to 2V, I OUT=0.2 A AM13869V1 DocID025316 Rev 3 , V OUT=5V, Tr =5µs AM13870V1 15/30 Typical characteristics LD39020 Figure 20: Turn-on time (VOUT = 1 V) Figure 21: Turn-off time (VOUT = 1 V) V IN V IN V OUT V OUT IOUT IOUT V IN = V EN = from 0V to 5.5 V, I OUT = 0.2 A V IN = V EN = from 5.5 V to 0 V, I OUT = 0.2 A , V OUT= 1 V, T f = 5µ s , V OUT = 1 V, T r = 5µ s AM13872V1 AM13871V1 Figure 22: Turn-on time (VOUT = 5 V) Figure 23: Turn-off time (VOUT = 5 V) V IN V IN V OUT IOUT V OUT IOUT V IN=V EN= from 0V to 5.5V, I OUT=0.2A V IN = V EN = from 5.5 V to 0V, I OUT = 0.2 A , V OUT= 5V, T f = 5µ s , V OUT=5V, Tr =5µs AM13873V1 AM13874V1 Figure 24: Line transient (VOUT = 1 V) Figure 25: Line transient (VOUT = 5 V) V IN V IN V OUT V OUT V IN = V EN =from 2V to 3V , I OUT=10 mA , V OUT= 1 V, T r =T f =5µ s V IN= V EN= from 5.1V to 5.5V , I AM13875V1 16/30 DocID025316 Rev 3 OUT= 10 m A , V OUT= 5 V, T r = T f = 5µ s AM13876V1 LD39020 Typical characteristics Figure 26: Load transient (VOUT = 1 V) Figure 27: Load transient (VOUT = 5 V) I O UT I O UT V O UT V O UT V IN=V EN=2 V, I OUT= from 0 to 0.2 A , V OUT= 1 V, t r =t f =5µ s V IN=V EN=5.5 V, I OUT= from 0 to 0.2 A , V OUT= 5 V, t r =t f =5µ s AM13877V1 DocID025316 Rev 3 AM13878V1 17/30 Package information 8 LD39020 Package information In order to meet environmental requirements, ST offers these devices in different grades of ECOPACK® packages, depending on their level of environmental compliance.
