NCP571

NCP571, NCV571 Voltage Regulator - CMOS, Low Iq, Low Output 150 mA The NCP571 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 NCP571 series features an ultra−low quiescent current of 4.0 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 NCP571 has been designed to be used with low cost ceramic capacitors and requires a minimum output capacitor of 0.1 mF. The device is housed in the TSOP−5 or DFN6 surface mount package. Standard voltage versions are 0.8 V, 0.9 V, 1.0 V and 1.2 V. Features Low Quiescent Current of 4.0 mA Typical Maximum Operating Voltage of 12 V Low Output Voltage Option down to 0.8 V High Accuracy Output Voltage of 3.0% Industrial Temperature Range of −40°C to +85°C (NCV571, TA = −40°C to +125°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 Battery Powered Instruments Hand−Held Instruments Camcorders and Cameras Vin 1 Thermal Shutdown Enable ON 3 Driver w/ Current Limit Vout 5 + OFF GND 2 Figure 1.
