1 / 10 page © Semiconductor Components Industries, LLC, 2007 March, 2007 − Rev. 0 1 Publication Order Number: NCP3520/D NCP3520/NCP3521 LDO Regulator Controller The NCP3520 / NCP3521 parts are Low Drop Out (LDO) regulator controllers for applications requiring high−currents and ultra low dropout voltages. The use of an external NMOS driver allows the user to adapt the device to a multitude of applications depending on system requirements for current and dropout voltage. Features • Fixed Voltage Options ♦ NCP3520 (1.2 V) ♦ NCP3521 (1.5 V) • Low Operating Current • Low Standby Current (sleep mode < 1 mA) • Non Rush Current on Startup • Short Circuit Protection • 1% Output Voltage Tolerance • Drop−In Replacement for Rohm BD3520FVM and BD3521FVM • Functionally Equivalent to the Rohm BD3501FVM and BD3502FVM • These are Pb−Free Devices Typical Applications • Computer based gaming consoles Figure 1.
