systems

• Digital still cameras.

Flip-chip 4

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.

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 μV_RMSfrom 1 kHz to 100

kHz at V_OUT= 1.8 V)

• Output voltage tolerance: ± 2.0 % @ 25 °C

• 300 mA guaranteed output current
