NCV511

NCP511, NCV511 Voltage Regulator - CMOS, Low Iq, Low-Dropout 150 mA The NCP511 series of fixed output low dropout linear regulators are designed for handheld communication equipment and portable battery powered applications which require low quiescent current. The NCP511 series features an ultra−low quiescent current of 40 mA. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, resistors for setting output voltage, current limit, and temperature limit protection circuits. The NCP511 has been designed to be used with low cost ceramic capacitors and requires a minimum output capacitor of 1.0 mF. The device is housed in the micro−miniature TSOP−5 surface mount package. Standard voltage versions are 1.5 V, 1.8 V, 2.5 V, 2.7 V, 2.8 V, 3.0 V, 3.3 V, and 5.0 V. Other voltages are available in 100 mV steps. Features Low Quiescent Current of 40 mA Typical Low Dropout Voltage of 100 mV at 100 mA Excellent Line and Load Regulation Maximum Operating Voltage of 6.0 V Low Output Voltage Option High Accuracy Output Voltage of 2.0% Industrial Temperature Range of −40°C to 85°C NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These are Pb−Free Devices Typical Applications Cellular Phones Battery Powered Instruments Hand−Held Instruments Camcorders and Cameras Vin 1 Thermal Shutdown Driver w/ Current Limit Vout 5 Enable ON 3 OFF G...
