SS6730-33CVTR

SS6730 150mA Low-Noise, Low-Dropout Linear Regulator FEATURES Output tolerance of ±2%. Output voltage of 1.8V to 3.3V with 0.1V increments. Active-low shutdown control. Very low quiescent current. Very low dropout voltage. Miniature package (SOT-23-5 & SOT-23-6W) Short-circuit and thermal protection. Very low noise. DESCRIPTION The SS6730 is a low noise, low dropout linear regulator, housed in a small SOT -23-5 o r SOT-23-6W package. The device is in the “ON” state when the SHDN pin is set to a logic-high level. An internal P -MOSFET pass transistor is used to achieve a low dropout voltage of 90mV at 50mA load current. It offers a high precision output voltage of ± 2%. The very low quiescent current and low dropout voltage make this device ideal APPLICATIONS Cellular Telephones. Pagers. Personal Communication Equipment. Cordless Telephones. Portable Instrumentation. Portable Consumer Equipment. Radio Control Systems. Low Voltage Systems. Battery Powered Systems. for battery powered applications. The internal reverse bias protection eliminates the requirement for a reverse voltage protection diode. The high ripple rejection and low noise provide enhanced An performance for critical can be applications. external capacitor connected to the noise bypass pin to reduce the output noise level.
