SULR1190
Technical Data
Data Sheet N1577, Rev. -
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.
