P-TO252-5-11
Functional Description
The TLE 4290 is a monolithic integrated low drop voltage
regulator which can supply loads up to 450 mA with
power good feature. An input voltage up to 42 V is
regulated to VQ,nom = 5.0 V. The device is designed to
supply μ-controllers in the severe environment of
P-TO263-5-1
automotive applications. Therefore it is protected against
overload, short circuit and over temperature conditions. Of course the TLE 4290 can
been used also in all other applications, where a stabilized 5 V voltage is required.
