Description
The LD39030SJ is a low noise voltage regulator
that provides 300 mA maximum current from an
input voltage in the 1.5 V to 5.5 V range, with a
typical dropout voltage of 200 mV. It is stabilized
with a ceramic capacitor on the output. 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 typically 62 dB at low frequencies and
starts to roll off at 10 kHz. An enable logic control
function puts the LD39030SJ 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.
