Description
The LD39020 high accuracy voltage regulator
provides 200 mA of maximum current from an
input voltage ranging from 1.5 V to 5.5 V, with a
typical dropout voltage of 200 mV.
It is available in DFN4 1x1 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 battery-
operated 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.

Application information
LD39020
12/30
DocID025316 Rev 4
6 Application information
6.1 Soft start function
The LD39020 has an internal soft start circuit. 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: "DFN4 1x1 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.
