MAS9160
2-Output LDO Voltage Regulator IC
Dual
Regulator: 2 150 mA
Very Low Crosstalk
Low Dropout: 70 mV
High Ripple Rejection: 60 dB
Low Noise: 30 Vrms
Stable with Low-ESR Output
Capacitors
Separate Enable/Disable Control
for Both Regulators
DESCRIPTION
MAS9160 is a voltage regulator IC with two low
dropout voltage regulators, which both have their
own enable/disable pin allowing the regulators to be
turned off or on separately by pulling the particular
control to low or high.
Due to the low noise level of only 30 Vrms,
MAS9160 is suitable for sensitive circuits, e.g., in
portable applications. In addition to the low noise
level, MAS9160 excels in dropout voltage (70 mV
typical at 50 mA) and in very good crosstalk
rejection. Also its ripple rejection ability of 60 dB at
1 kHz exceeds that of competition.
A wide range of values of Equivalent Series
Resistance (ESR) of output capacitors can be used
with MAS9160. This ESR range from a few m up
to a couple of Ohms combined with no minimum
output current requirement makes the usage of
MAS9160 easier and low in cost.
In order to save power the device goes into sleep
mode when both regulators are disabled. An internal
thermal protection circuit prevents the device from
overheating. Also the maximum output current is
internally limited.
