AP7362 1.5A, LOW QUIESCENT CURREENT, FAST TRANSIENT ULTRA-LOW DROPOUT LINEAR REGULATOR Description Pin Assignments The AP7362 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. The integrated 857 6 Enable block allows the part to be turned on and off via a logic signal. A logic high level on EN turns the device on and a logic low turns the part off. The low dropout voltage characteristics and fast transient response to step changes in load make it suitable for low voltage microprocessor 142 3 GND EN IN IN applications. The typical quiescent current is approximately 0.5mA U-DFN2030-8 and changes little with load current. The built-in current-limit and thermal-shutdown functions prevent damage to the IC in fault (Top View) conditions.

EN 2 Enable input, active high. IN 3, 4 Voltage input pin. OUT 5, 6, 7 Voltage output pin. Output feedback pin for adjustable version only a resistor divider from this pin to the OUT pin and ADJ 8 ground sets the output voltage. NC 8 No connection for fixed output version. The exposed pad (EP) is used to remove heat from the package and it is recommended that it is EP EP 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.
