AP033

AP033 1.5A Low Dropout Positive Fixed-Mode Regulator „ Features „ General Description AP033 is a low dropout positive fixed-mode regulator with minimum of 1.5A output current capability. The product is specifically designed to provide well-regulated supply for low voltage IC applications such as high-speed bus termination and low current 3.3V logic supply. AP033 is guaranteed to have <1.4V dropout at full load current making it ideal to provide well regulated outputs of 3.3V with 4.7V to 12V input supply by different output voltage. 3-Terminal and Fixed 3.3V 1.4V Maximum Dropout at Full Load Current. Fast Transient Response. Built-in Thermal Shutdown. Output Current Limiting. „ Applications PC peripheral Communication „ Ordering Information AP 033 X X X LDO Regulator 033 Vout = 3.3V Package Lead Free Packing Blank : Tube A : Taping D : TO252-3L Blank : Normal L : Lead Free Package „ Pin Assignments 3 PIN TO252 3 2 1 Tab is GND VOUT GND VIN „ Pin Descriptions Name Pin # Function The input pin of regulator. Typically a large storage capacitor is connected from this pin to ground to insure that the input voltage does not sag below the minimum dropout voltage during the load transient response. This pin must always be 1.4V higher than VOUT in order for the device to regulate properly. Ground The output of the regulator. A minimum of 10µF capacitor must be connected from this pin to ground to insure stability. Ground VIN 1 GND VOUT 2 3 This datasheet con...
