5-V LOW-DROPOUT VOLTAGE

REGULATOR



DESCRIPTION

The UTC ULE4275 is a monolithic integrated low-dropout

voltage regulator. The device regulates an input voltage up to

450mA.

It

also

provides

overcurrent

protection

and

overtemperature protection for control of the state of the output

voltage. The device generates a reset signal for an output

capacitor, one can program the reset delay time.

the oscillation of input inductance and input capacitance. The

operating temperature range.

The control amplifier compares a reference voltage to a voltage that is proportional to the output voltage and

drives the base of the series transistor through a buffer. Saturation control as a function of the load current prevents

any oversaturation of the power element. The device also incorporates a number of internal circuits for protection

against: overload, overtemperature, and reverse polarity.


