MAS9130
150 mA LDO Voltage Regulator IC
Low Noise: 20 Vrms
Low Minimum Output Capacitance
Requirement: 0.22 F
Excellent Ripple Rejection: 65 dB
Very Low Dropout: 70 mV
Regulator Enable/Disable Control
Stable with Low-ESR Output
Capacitors
DESCRIPTION
MAS9130 is a low dropout voltage regulator with an
enable/disable pin, which allows device to be turned
off or on by pulling control to low or high.
Due to the low noise level of only 20 Vrms,
MAS9130 is suitable for sensitive circuits, e.g., in
portable applications. In addition to the noise levels,
MAS9130 excels in dropout voltage (70 mV typical
at 50 mA) and rise time (16 s typical without
bypass capacitor). Also its ripple rejection ability of
65 dB at 10 kHz exceeds that of competition.
The Equivalent Series Resistance (ESR) range of
output capacitors that can be used with MAS9130 is
very wide. This ESR range from a few m up to a
couple of Ohms combined with no minimum output
current requirement makes the usage of MAS9130
easier and low in cost.
In order to save power the device goes into sleep
mode when the regulator is disabled. MAS9130 also
includes an auto-discharge function, wherein a
shutdown transistor turns on and discharges the
output capacitor. An internal thermal protection
circuit prevents the device from overheating. Also
the maximum output current is internally limited.
