MC33765

Very Low Dropout/

Ultra Low Noise

5 Outputs Voltage Regulator

The MC33765 is an ultra low noise, very low dropout voltage

regulator with five independent outputs which is available in TSSOP

16 surface mount package.

The MC33765 is available in 2.8 V. The output voltage is the same

for all five outputs but each output is capable of supplying different

currents up to 150 mA for output 4. The device features a very low

dropout voltage (0.11 V typical for maximum output current), very

low quiescent current (5.0

mA maximum in OFF mode, 130 mA typical

in ON mode) and one of the output (output 3) exhibits a very low noise

level which allows the driving of noise sensitive circuitry. Internal

current and thermal limiting protections are provided.

Additionally, the MC33765 has an independent Enable input pin for

each output. It includes also a common Enable pin to shutdown the

complete circuit when not used. The Common Enable pin has the

highest priority over the five independent Enable input pins.

The voltage regulators VR1, VR2 and VR3 have a common input

voltage pin VCC1.

The other voltage regulators VR4 and VR5 have a common input

voltage pin VCC2.
