Housed in a Micro8 or QFN6 package, the MC33263 delivers up to 150 mA where it exhibits a typical 180 mV dropout. With an incredible noise level of 25 VRMS (over 100 Hz to 100 kHz, with a 10 nF bypass capacitor), the MC33263 represents the ideal choice for sensitive circuits, especially in portable applications where noise performance and space are premium. The MC33263 also excels in response time and reacts in less than 25 s when receiving an OFF to ON signal (with no bypass capacitor)

FEATUREs:
• Very Low Quiescent Current 170 μA (ON, no load), 100 nA (OFF, no load)
• Very Low Dropout Voltage, Typical Value is 137 mV at an Output Current of 100 mA
• Very Low Noise with External Bypass Capacitor (10 nF), Typically 25 μVrms over 100 Hz to 100 kHz
• Internal Thermal Shutdown
• Extremely Tight Line Regulation Typically −90 dB
• Ripple Rejection −70 dB @ 1.0 kHz
• Line Transient Response: 1.0 mV for Vin = 3.0 V
• Extremely Tight Load Regulation, Typically 20 mV at Iout = 150 mA
• Multiple Output Voltages Available
• Logic Level ON/OFF Control (TTL−CMOS Compatible)
• ESR can vary from 0 to 3.0 

APPLICATIONs:
• All Portable Systems, Battery Powered Systems, Cellular Telephones, Radio Control Systems, Toys and Low Voltage Systems
