MAS9162

80 mA LDO Voltage Regulator IC

• Low Noise, 30 µVrms, without

External Bypass Capacitor

• Very Short Start-up Time: 10 µs

• Stable with Low-ESR Output

Capacitors

• Low Minimum Output Capacitance

Requirement: 0.25 µF

• Regulator Enable/Disable Control

DESCRIPTION

MAS9162 is a low dropout voltage regulator, which

achieves the low output noise level of 30 µVrms

without an external bypass capacitor. MAS9162

features very fast start-up time (typically only 10 µs

from start-up to within ±1% of VOUT(NOM)) and low

dropout voltage (80 mV typical at 50 mA).

The minimum output capacitance requirement is

very low. This with the very short start-up time

makes it possible to switch the regulator off and on

even in timing critical and/or noise sensitive

applications. In order to save power the device

enters the sleep mode when the regulator is

disabled.

The Equivalent Series Resistance (ESR) range of

output capacitors that can be used with MAS9162 is

very wide. This ESR range from a few mΩ up to a

couple of Ohms combined with no minimum output

current requirement makes the usage of MAS9162

easier and low in cost.

An internal thermal protection circuit prevents the

device from overheating. Also the maximum output

current is internally limited.
