4 date: 6/15/06 rev ab sp6222/6223 50/150ma cmos linear regulators ? 2006 sipex corporation general overview the sp6222 and sp6223 are cmos ldos designed to meet a broad range of low voltage applications that require accuracy and ease of use. the sp6222 offers a 50ma output current while the sp6223 offers an output current of 150ma. the sp6222 is available in a 2.5v or 3.0v fixed output along with an adjustable output version. the sp6223 is offered in an adjustable output only. these ldos have a minimum input voltage of only 1.6v and a maximum input voltage of 4.5v. the output voltage can be programmed to as low as 0.9v and have a maximum dropout voltage rating of 100mv for the sp6222 and 300mv for the sp6223. both devices are equipped with an enable (en) input for very low current (10na typical) shutdown mode. enable / shutdown operation the sp6222/6223 is turned on by providing 1.6v or greater to the en pin. to place the device into shutdown pull the en pin below 0.4v. if this feature is not required connect en to input supply to always enable the device whenever power is applied. input / output capacitor the sp6222/6223 is designed to operate using very small ceramic capacitors. the minimum input and output capacitor value for stable operation is 1.0 f. the output capacitor value may be increased without limit to improve transient response. place these capacitors as close as possible to the device. bypass (byp) capacitor the fixed output versions offer a byp pin to decouple the bandgap reference. connecting an external 10nf capacitor from byp to gnd can reduce output noise. if output noise is not a concern the byp pin may be left open. when a bypass capacitor is used the turn on time is slower. see the following turn on time plots for various byp capacitor values. the adjustable output version does not offer this byp input. adjustable regulator the output of the device can be programmed to a specific voltage by using two external resistors connected to the adj pin (see typical application circuit for adjustable output). the resistors set application information
5 date: 6/15/06 rev ab sp6222/6223 50/150ma cmos linear regulators ? 2006 sipex corporation the output voltage based on the following equation: v out = v ref *(r1/r2 + 1) resistor values are not critical because the adj (adjust) pin has a high impedance, but for best performance use resistor values of 470k or less. thermal considerations the sp6222/6223 is designed to provide 50ma -150ma of continuous current in a tiny package. maximum power dissipation can be calculated based on the output current and the voltage drop across the part. to determine the maximum power dissipation of the package, use the junction-to-ambient thermal resistance of the device and the following equation: p d(max) = (t j(max) C t a ) / ja t j(max) is the maximum junction temperature of the die and is 125 o c. t a is the ambient temperature. ja is the junction-to-ambient thermal resistance of the package. the sot- 23 package has a ja of approximately 191 o c/w and the sc70 package has a ja of approximately 330 o c/w. the actual power dissipation of the regulator circuit can be determined by using the simplified equation: p d = (v in C v out ) * i out to prevent the device from entering thermal shutdown, maximum power dissipation cannot be exceeded. layout considerations the primary path of heat conduction out of the package is via the package leads. therefore, careful consideration must be taken into account for optimizing layout. 1. attaching the part to a large copper footprint will enable better heat transfer from the device, especially where there are internal ground and power planes. 2. place the input and output capacitors close to the device for optimal transient response and device behavior. 3. connect all ground connections directly to the ground plane. in case there is no ground plane, connect to a common ground point before connecting to board ground. application information
