systems
• Digital still cameras.
Description
Flip-chip 4
Features
• Input voltage from 1.5 to 5.5 V
• Ultra low dropout voltage (200 mV typ. at 300
mA load)
• Very low quiescent current (20 μA typ. at no
load, 40 μA typ. at 300 mA load, 1 μA max. in
off mode)
• Very low noise (30 μVRMS from 1 kHz to 100
kHz at VOUT = 1.8 V)
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.
• Output voltage tolerance: ± 2.0 % @ 25 °C

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 time measured between the enable input just exceeding VEN high value and the output voltage just
reaching 95 % of its nominal value.

Soft-start function
Soft-start function
The LD39030S has an internal soft-start circuit. By increasing the startup time up to 100 μs,
without the need of any external soft-start capacitor, this feature is able to reduce the
regulator inrush current to 1/3 of the original value.
