1 / 12 page © Semiconductor Components Industries, LLC, 2004 August, 2004 − Rev. 9 1 Publication Order Number: NCP551/D NCP551, NCV551 150 mA CMOS Low Iq Low−Dropout Voltage Regulator The NCP551 series of fixed output low dropout linear regulators are designed for handheld communication equipment and portable battery powered applications which require low quiescent. The NCP551 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 NCP551 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 micro−miniature TSOP−5 surface mount package. Standard voltage versions are 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.2, 3.3, and 5.0 V. Other voltages are available in 100 mV steps. Features • Low Quiescent Current of 4.0 mA Typical • Maximum Operating Voltage of 12 V • Low Output Voltage Option • High Accuracy Output Voltage of 2.0% • Industrial Temperature Range of −40°C to 85°C (NCV551, TA = −40°C to +125°C) • NCV Prefix for Automotive and Other Applications Requiring Site and Control Changes • Pb−Free Packages are Available Typical Applications • Battery Powered Instruments • Hand−Held Instruments • Camcorders and Cameras Figure 1.
