The ILC7280 is two independent 150mA low dropout (LDO)
voltage regulators in an 8-pin MSOP package. Each regu-
lator output is independently short circuit protected and has
independent enable lines. The device offers a unique com-
bination of low dropout voltage and low quiescent current of
CMOS as well as the low noise and high ripple rejection
characteristics of bipolar LDO regulators. Moreover, only
one input capacitor is required.
Dropout Voltage:
Typically 150mV at 150mA load, and
1mV at 1mA load.
Ground pin current:
Typically 130μA at 1mA load, and
135μA at 150mA load.
Ripple Rejection:
55dB at 1kHz and 60dB at 100kHz.
Shutdown mode:
Less than 0.5μA quiescent current in
shutdown mode.
Small package:
MSOP-8
Small capacitor:
Requires only a 0.47μF external capacitor
on the regulator output.
Precision output:
Output voltage trimmed to 1% accuracy.
Output Noise:
80μV
