Description

The LDLN015 is an ultra low noise linear

regulator which provides 150 mA maximum

current from an input voltage ranging from 2.1 V

to 5.5 V with a typical dropout voltage of 86 mV.

Hz to 100 kHz, the LDLN015 provides a very

clean output suitable for ultra sensitive loads. It is

stable with ceramic capacitors. High PSRR, low

quiescent current and very low noise features

make it suitable for low power battery powered

applications. Power supply rejection is higher

than 90 dB at low frequencies and starts to roll off

at 10 kHz. The enable logic control function puts

the LDLN015 into shutdown mode allowing a total

current consumption lower than 1 µA. The device

also includes a short-circuit constant current

limiting and thermal protection. Typical

applications are noise sensitive loads like ADC,

VCO in mobile phones, and personal digital

assistants (PDAs).
