The
IFX20002
is not qualified and manufactured according to the requirements of Infineon Technologies with
regards to automotive and/or transportation applications. For automotive applications please refer to the Infineon
TLx (TLE, TLS, TLF.....) voltage regulator products.
Description
The
IFX20002
is a monolithic integrated low drop voltage regulator in a very small SMD package PG-SCT595-5.
It is designed to supply e.g. micro controller, sensors, etc or may serve as standby supply under severe conditions.
Therefore the device is equipped with additional protection functions against overload, short circuit and reverse
polarity. At over temperature the regulator is automatically turned off by the integrated thermal protection circuit.
Input voltages up to 40 V are regulated to
V
Q,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 in stand-by mode via an inhibit input which causes the current consumption to drop below 5
μA.

ESD Susceptibility
1) Not subject to production test, specified by design.
2) Internally limited.
3) ESD susceptibility, HBM according to ANSI/ESDA/JEDEC JS-001 (1.5 k
Ω
, 100 pF).
Note: Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Note: Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are
not designed for continuous repetitive operation.
