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
TSSOPâ16 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.
