A6300A
LOW DROPOUT VOLTAGE REGULATOR
300mA CMOS ULTRA LOW NOISE AND FAST RESPONSE
DESCRIPTION
The A6300A is designed for portable RF and wireless
applications with demanding performance and space
requirements.
The A6300A performance is optimized for
battery-powered systems to deliver ultra low noise and
low quiescent current. A noise bypass pin is available for
further reduction of output noise. Regulator ground
current increases only slightly in dropout, further
prolonging the battery life.
The A6300A also works with low- ESR ceramic
capacitors, reducing the amount of board space
necessary for power applications, critical in hand-held
wireless devices.
The A6300A consumes less than 0.01μA in shutdown
mode and has fast turn-on time less than 50μs. The
other features include ultra low dropout voltage, high
output accuracy, current limiting protection, and high
ripple rejection ratio.
The A6300A is available in SOT-23 and SOT-25
packages.
