NCP571, NCV571 150 mA CMOS Low Iq Low Output Voltage Regulator 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. http://onsemi.com 6 5 1 1 TSOP−5 SN SUFFIX CASE 483 DFN6 MN SUFFIX CASE 506BA 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 Site and Change Controls These are Pb−Free Devices Typical Applications • Battery Powered Instruments • Hand−Held Instruments • Camcorders and Cameras Vin XXXAYWG G XXX A Y W M G 1 XX MG G = Specific Device Code = Assembly Location = Year = Work Week = Date Code = Pb−Free Package (Note: Microdot may be in either location) 1 5 Thermal Shutdown MARKING DIAGRAMS Vout ORDERING INFORMATION Driver w/ Current Limit See detailed ordering and shipping information in the package dimensions section on page 10 of this data sheet. + Enable ON 3 OFF GND 2 Figure 1.

Larger values improve noise rejection and load regulation transient response. Input Decoupling (C1) Enable Operation A 0.1 mF capacitor either ceramic or tantalum is recommended and should be connected close to the NCP571 package. Higher values and lower ESR will improve the overall line transient response. The enable pin will turn on or off the regulator. These limits of threshold are covered in the electrical specification section of this data sheet. If the enable is not used then the pin should be connected to Vin. It is not recommended to leave this pin on air. In case the voltage of Enable signal is higher then Input voltage of NCP571 device it is necessary add an resistor divider in order to keep voltage at Enable pin bellow Input voltage. A single gate device of VHC family could be used for this logic level translation. The NL17SZ06 device could be chosen for non inverting open−drain buffer as shown in Figure 19. Other possibility is using NL17SZ16 device as shown in Figure 20. More information is mentioned in Application Note AND8101/D. Output Decoupling (C2) The NCP571 is a stable Regulator and does not require any specific Equivalent Series Resistance (ESR) or a minimum output current. Capacitors exhibiting ESRs ranging from a few mW up to 3.0 W can thus safely be used. The minimum decoupling value is 0.1 mF and can be augmented to fulfill stringent load transient requirements. The regulator accepts ceramic chip capacitors as well as tantalum devices.

Hints conductivity through the PCB, the junction temperature will be relatively low with high power dissipation applications. The maximum dissipation the package can handle is given by: Please be sure the Vin and GND lines are sufficiently wide. When the impedance of these lines is high, there is a chance to pick up noise or cause the regulator to malfunction. Set external components, especially the output capacitor, as close as possible to the circuit, and make leads as short as possible. PD + T J(max) * T A R qJA If junction temperature is not allowed above the maximum 125°C, then the NCP571 can dissipate up to 400 mW @ 25°C. The power dissipated by the NCP571 can be calculated from the following equation: Thermal As power across the NCP571 increases, it might become necessary to provide some thermal relief. The maximum power dissipation supported by the device is dependent upon board design and layout. Mounting pad configuration on the PCB, the board material, and also the ambient temperature effect the rate of temperature rise for the part.
