1 Technology Licensed from International Rectifier APU0///9-HF- A Low Drop-out Positive Voltage Regulators Features Low dropout voltage (00mV at A load) Voltage reference accuracy of % Low ground current Maximum quiescent current in shutdown of µa (APU0M-, APU0M-) Fast transient response Current limit and thermal shutdown Error flag signal for "output out of regulation" (APU0M-, APU0M-) RoHS-compliant, halogen-free package Applications Supplying.V output from.v input for the new generation of ICs Computer motherboard and add-on cards High efficiency post-regulator in switched-mode power supplies (SMPS) Description The APU0 family of devices are ultra-low dropout A linear regulators using a PNP transistor as the pass element. These products are ideal when only a single input supply is available and the required dropout voltage is less than V, exceeding the minimum dropout characteristics of NPN/PNP hybrid regulators. One common application of these regulators is where the input is.v and a.v output is needed. Along with the low dropout voltage of less than 0.V, other features of this family of parts are micro-power shutdown capability and output UVLO detection where the Flag pin is switched low when the output falls below % of its nominal point.

Typically a large storage capacitor is connected from this pin to ground to ensure that the input voltage does not sag below the minimum drop-out voltage during the load transient response. This pin must always be 0.V higher than in order for the device to regulate properly. The output of the regulator. A capacitor of at least.µf must be connected from this pin to ground. Ground pin. This pin must be connected to the lowest potential in the system and all other pins must be at higher potential with respect to this pin. pin. A low signal or left open on this pin shuts down the output. This pin must be tied HI or to for normal operation. An open collector output that switches low when the output voltage drops about % below its expected regulated voltage. A resistor divider from this pin to the pin and ground sets the output voltage. Application Information Stability The APU0X series of regulators requires the use of an output capacitor as part of the frequency compensation in order to make the regulator stable. A capacitor of at least.µf and ESR in the range of 0. to Ω will ensure the stability of the system. Typical Applications APU0-XX C C Note: Tab must also be connected to ground.
