Description
The LD39115Jxx provides 150 mA maximum
current from an input voltage ranging from 1.5 V
to 5.5 V with a typical dropout voltage of 80 mV. It
is stabilized with a 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. An enable logic control function
puts the LD39115Jxx in shutdown mode allowing
a total current consumption lower than 1 µA. The
device also includes a short-circuit constant
current limiting and thermal protection.
