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  ifferent 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 A maximum in OFF mode, 130 A 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.
