AMS73XX Features · Low power consumption · High output current : 300mA · Low voltage drop · Output voltage accuracy: tolerance ±2% · Low temperature coefficient · TO-92, SOT-89 and SOT-23 package · High input voltage (up to +18~24V) Applications · Battery-powered equipment · Audio/Video equipment · Communication equipment General Description The AMS73XX series is a set of three-terminal high current low voltage regulator implemented in CMOS technology. They can deliver 300mA output current and Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents. allow an input voltage as high as 20V. They are available with several fixed output voltages ranging from 1.5V to 5.0V. CMOS technology ensures low voltage drop and low quiescent current.
