Preliminary

LINEAR INTEGRATED CIRCUIT

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

45V to V_OUT= 5V (typical). The device can drive loads 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

voltage, V_OUT,rt, of 4.65V (typical). By the use of an external delay

capacitor, one can program the reset delay time.

The input capacitor, C_IN, compensates for line fluctuation.

Using a resistor of approximately 1Ω in series with C_INdampens

the oscillation of input inductance and input capacitance. The

output capacitor, C_OUT, stabilizes the regulation circuit. The

specification for stability is at C_OUT≥ 22μF and ESR ≤ 5Ω, within

the operating temperature range. Stability for electrolytic capacitors specifically is at C_OUT≥ 68µF within 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.
