AX6606
600mA LDO Linear Regulator
GENERAL DESCRIPTION
The AX6606 is a low dropout, positive linear regulator with very low quiescent. It can
supply up to 600mA output current. The BP pin with a 10nF bypass capacitor can help
reduce the output noise level. The characteristics of low dropout voltage and less quiescent
current make it good for some critical current application, for example, some battery
powered devices. The typical quiescent current is approximately 50µA. In the shutdown
mode, the maximum supply current is less than 1uA. The AX6606 regulator is able to
operate with output capacitors as small as 2.2uF for stability. The AX6606 series are offering
several fixed output voltage types including 1.0V, 1.1V, 1.2V, 1.3V and 1.4V. Built-in
current-limit and thermal-shutdown functions prevent any fault condition from IC damage.

AX6606
Current Limit and Thermal Shutdown Protection
In order to prevent overloading or thermal condition from damaging the device,
AX6606 regulator has internal thermal and current limiting functions designed to protect the
device. It will rapidly shut off PMOS pass element during overloading or over temperature
condition.
Thermal Considerations
The AX6606 series can deliver a current of up to 600mA over the full operating junction
temperature range. However, the maximum output current must be dated at higher ambient
temperature to ensure the junction temperature does not exceed 125°C. With all possible
conditions, the junction temperature must be within the range specified under operating
conditions. Power dissipation can be calculated based on the output current and the voltage
drop across regulator.
PD = (VIN - VOUT) IOUT
The final operating junction temperature for any set of conditions can be estimated by
the following thermal equation:
PD (MAX) = (TJ (MAX) - TA) / θJA
Where TJ (MAX) is the maximum junction temperature of the die (125°C) and TA is the
maximum ambient temperature. The junction to ambient thermal resistance (θJA) for
SOT-23-5L package at recommended minimum footprint is 250°C/W.
