MAS9168
150 mA LDO Voltage Regulator IC
• Only 15.5 µA Ground Pin Current
at 1 mA Load Current
• Good Transient Performance
• Low Dropout Voltage
• Low Noise
• Enable/Disable Control
• Stable with Low-ESR Output
Capacitors
This is preliminary information on a new product under
development. Micro Analog Systems Oy reserves the right
to make any changes without notice.
DESCRIPTION
MAS9168 LDO voltage regulator is optimized for
operation at low ground pin current: even at 50 mA
load current its ground pin current is only 40 µA.
This combined with the good overall performance
makes MAS9168 very suitable for providing
continuous supply in low power circuits. The
performance of MAS9168 benefits applications
where standby periods are long and where long
battery lifetime is essential.
The Equivalent Series Resistance (ESR) range of
output capacitors that can be used with MAS9168
is very wide. This ESR range from zero up to a
couple of Ohms combined with no minimum output
current requirement makes the usage of MAS9168
easier and low in cost.
Enable/disable pin allows MAS9168 to be turned off
and on. In order to save power the device enters
the sleep mode when the regulator is disabled.
In addition to the low ground pin current, MAS9168
excels in dropout voltage (220 mV typical at
150 mA). Even though MAS9168 does not use an
external bypass capacitor, the noise level
(100 Hz… 100 kHz) is only 70 µVrms with 1 µF
output capacitor.
An internal thermal protection circuit prevents the
device from overheating. Also the maximum output
current is internally limited.

APPLICATION INFORMATION
Auto-Discharge Function
where TJMAX is maximum junction temperature
(TJMAX = 125°C), TA is ambient temperature and RJA
is junction-to-ambient thermal resistance of the
package.
MAS9168 does not feature an auto-discharge
function. The voltage in VOUT pin, when MAS9168
is turned off, depends on the load circuits leakage:
if the load has big leakage current, VOUT rapidly
drops to the value 0 V, but if the leakage current is
non-existing, VOUT pin stays in VOUT(NOM) value.
When assumed that:
TA = +55°C, VOUT = 1.8 V, VIN = 5.0 V and used
package is TSOT-5 the equation yields:
Calculating Maximum Power Dissipation
125°C − 55°C
207°C/W
Maximum power dissipation of the package may
limit output current or input voltage, which can be
used, especially with the combination of low output
voltage and high input voltage.
P

= 0.338 W

from which can be calculated:

The power dissipation can be calculated by using
the formula:

It shall not exceed the maximum power dissipation,

Consequently, it can be seen that under these
conditions the average output current should not
exceed 106 mA.
