CMOS LOW DROPOUT REGULATOR (LDO)

300mA ULTRA-LOW NOISE, ULTRA-FAST RESPONSE

DESCRIPTION

FEATURES

The A6303A is designed for portable RF and

wireless applications with demanding

performance and space requirements.

The A6303A performance is optimized for

battery –powered systems to deliver ultra low

noise and low quiescent current. Regulator

ground currentincreases only slightly in dropout,

furtherprolonging the battery life.



Ultra-low Noise for RF Application

Ultra-Fast Response in Line/Load Transient

<0.01μA Standby Current When Shutdown

Low Dropout: 210mV@300mA

Wide Operating Voltage Ranges: 2V to 6V

Wide Output Voltage Range:1.2V to 5V

TTL-logic-Controlled Shutdown Input

(SOT-25, SC70-5)



Low Temperature Coefficient

The A6303A also works with low-ESR ceramic

capacitors, reducing the amount of board space

necessary for power applications, critical in

hand-held wireless devices. The A6303A

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.

Current Limiting Protection

Thermal Shutdown Protection

Only 1μF Output Capacitor Required for Stability

High Power Supply Rejection Ratio
