Description
The LD39015XX series provides 150 mA
maximum current from an input voltage ranging
Table 1.
SOT23-5L
from 1.5 V to 5.5 V with a typical dropout voltage
of 80 mV. It is stable with ceramic capacitor. The
ultra-low drop voltage, low quiescent current and
low noise features make it suitable for low power
battery-powered applications. Power supply
rejection is 65 dB at low frequencies and starts to
roll off at 10 kHz. Enable logic control function
puts the LD39015XX in shut-down mode allowing
a total current consumption lower than 1 µA. The
device also includes short-circuit constant current
limiting and thermal protection. Typical
applications are mobile phones, personal digital
assistants (PDAs), cordless phones or similar
battery-powered systems.

1. For VOUT(NOM) < 1.2 V, VIN = 1.5 V
2. All transient values are guaranteed by design, not production tested
3. Dropout voltage is the input-to-output voltage difference at which the output voltage is 100 mV below its nominal value. This
specification does not apply for output voltages below 1.5 V
4. Turn-on time is the time measured between the enable input just exceeding VEN High Value and the output voltage just
reaching 95 % of its nominal value
