Description
The IFX20001 is a monolithic integrated low drop voltage regulator in a very small SMD package PG-SCT595-5.
It is designed to supply various loads (e.g. microcontrollers, sensors, or as stand-by supply, etc.) under severe
conditions. Therefore the device is equipped with additional protection functions against overload, short
circuit and reverse polarity. In case of an overtemperature condition the regulator is automatically turned off
by the integrated thermal protection circuit.

IFX20001
Low dropout voltage regulator
Input voltages up to 40 V are regulated to VQ,nom = 3.3 V (V33 version) or 5.0 V (V50 version). The output is able
to drive a load of 30 mA while it regulates the output voltage within a 4% accuracy. To save energy the device
can be switched to stand-by mode via an inhibit input which causes the current consumption to drop below
5 µA.

Application diagram
The output voltage of the IFX20001 is divided and compared to an internal reference of 2.5 V typical.
A regulation loop controls the output to achieve a stabilized output voltage.
Figure 3 shows a typical application circuit. In order to maintain the stability of the control loop the IFX20001
output requires an output capacitor CQ of at least 3.3 µF with a minimum required ESR of 2.5 Ω and a maximum
allowed ESR of 6 Ω for the IFX20001MBV33 and 8 Ω for the IFX20001MBV50. It is recommended to use for CQ a
suitable tantalum capacitor or a multilayer ceramic capacitor with a sufficiently dimensioned series resistor
in order to cover the required ESR range over the full operating temperature range of Tj = -40°C to +125°C.1)
At the input of the regulator a capacitor is required for compensating line influences (100 nF ceramic capacitor
recommended). A resistor of approximately 1 Ω in series with the input capacitor CI can dampen oscillations
that could occur due to the input line inductance and the input capacitor.
1) For usage of ceramic capacitors without applying an additional series resistor at the output please refer to the IFX20002 which is
a corresponding voltage regulator series specially designed for the usage of low-ESR output capacitors (< 2 Ω).
