AP7363 1.5A LOW QUIESCENT CURRENT, FAST TRANSIENT ULTRA-LOW DROPOUT LINEAR REGULATOR Description Pin Assignments The AP7363 is a 1.5A adjustable output voltage linear regulator with (Top View) ultra-low dropout. The device includes pass element, error amplifier, ADJ/ OUT OUTOUT NC band-gap, current limit and thermal shutdown circuitry. 857 6 The characteristics of low dropout voltage and fast transient response to step changes in load make it suitable for low voltage microprocessor applications. The typical quiescent current is approximately 0.5mA and changes little with load current. The built-in current-limit and thermal-shutdown functions prevent IC from damage in fault conditions. 142 3 This device is available in U-DFN2030-8, SO-8EP, SOT223 and GND IN IN IN TO252 packages.

The exposed pad (EP) is used to remove heat from the package and it is recommended that EP/TAB it is connected to a copper area. The die is electrically connected to the exposed pad. It is recommended to connect it externally to GND, but should not be the only ground connection.
