Overview

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 µA maximum in OFF mode, 130 µA 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.

  • Five Independent Outputs at 2.8V Typical, based upon voltage version
  • Internal Trimmed Voltage Reference
  • Vout Tolerance +/- 3.0% over the Temperature Range -40°C to +85°C
  • Enable Input Pin (Logic-Controlled Shutdown) for Each of the Five Outputs
  • Common Enable Pin to Shutdown the Whole Circuit
  • Very Low Dropout Voltage (0.11 V Typical for Output 1, 2, 3 and 5; 0.17 V Typical for Output 4 at Maximum Current)
  • Very Low Quiescent Current (Maximum 5.0 mA in OFF Mode, 130 mA Typical in ON Mode)
  • Ultra Low Noise for VR3 (30 mV RMS Max, 100 Hz < f < 100 kHz)
  • Internal Current and Thermal Limit
  • 100 nF for VR1, VR2, VR4 and VR5 and 1.0 mF for VR3 for Stability
  • Supply Voltage Rejection: 60 dB (Typical) @ f = 1.0 kHz
  • These are Pb-Free Devices
