Description
DFN6 (2 x 2 mm)
The LDLN015 is an ultra low noise linear
regulator which provides 150 mA maximum
current from an input voltage ranging from 2.1 V
Features
• Ultra low noise: 6.3 µV_RMS from 10 Hz to
100 kHz
• Input voltage from 2.1 to 5.5 V
• Very low quiescent current (35 µA typ. at no
load, 70 µA typ. at 150 mA load; 2 µA max. in
off mode)
to 5.5 V with a typical dropout voltage of 86 mV.
With its 6.3 µV_RMS noise value in a band from 10
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
• Output voltage tolerance: ± 1% at 25 °C
• 150 mA guaranteed output current
• Wide range of output voltage from 0.8 V to
3.3 V with 100 mV step
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
• Logic-controlled electronic shutdown
• Compatible with ceramic capacitor
(C_OUT = 0.47 µF)
applications are noise sensitive loads like ADC,
VCO in mobile phones, and personal digital
assistants (PDAs).
• No bypass capacitor is required
