Ultra LDO 1A Linear Regulator With

Description:

A low noise, high PSRR and ultra low dropout linear regulator SULR1190 is optimized for low ESR

ceramic capacitors operation with 1A continuous current.

The SULR1190 offers high precision output voltage of ±2% tolerance. Output voltage can also be

adjusted for those other than the preset values.

A noise bypass pin is available for further reduction of output noise. The bypass pin could be floating

if it’s unnecessary. At 1A load current and 2.8V output voltage, a 440mV dropout is performed. The

quality of low quiescent current and low dropout voltage makes this device ideal for battery power

applications. The high ripple rejection and low noise of the SULR1190 provide enhanced performances

for critical applications such as cellular phones, and PDAs.

In addition, a logic-level shutdown input is included, which reduce supply current to less than 0.1μA

(typ.) in shutdown mode with fast turn-on time less than 100μs. The SULR1190’s current limit and

thermal protection provide protection against any overload condition that would create excessive

junction temperatures.

Features:

•

Guaranteed 1A Output Current.

•

Fast Response in Line/Load Transient

Wide Operating Voltage Ranges: 2.3V to 6.0V.

0.1μA Shutdown Standby Current
