Note 1: Exceeding the absolute maximum rating may damage the device.
Note 2: The device is not guaranteed to function outside its operating rating.
Note 3: The maximum allowable power dissipation at any TA (ambient temperature) is calculated using: PD(MAX)
=
(TJ(MAX) – TA)/ΘJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature,
and the regulator will go into thermal shutdown. See “Thermal Consideration” section for details
Note 4: Output voltage temperature coefficient is the worst case voltage change divided by the total temperature range.
Note 5: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested
for load regulation in the load range from 0.1mA to 150mA. Changes in output voltage due to heating effects are
covered by the thermal regulation specification.
Note 6: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its
nominal value measured at 1V differential.

Application Hints
Thermal Considerations
Like any low dropout regulator, SE5166 requires It is important that the thermal limit of the package is
external capacitors to ensure stability. The not exceeded. The SE5166 has built-in thermal
external capacitors must be carefully selected to protection. When the thermal limit is exceeded,
ensure performance.
the IC will enter protection, and VOUT will be pulled
to ground. The power dissipation for a given
application can be calculated as following:
Input Capacitor
An input capacitor of at least 2.2µF is required.
Ceramic or Tantalum can be used. The value can
be increase without upper limit.
The power dissipation (PD) is
PD = IOUT * [VIN – VOUT
]
Output Capacitor
An output capacitor is required for stability. It must The thermal limit of the package is then limited to
be placed no more than 1 cm away from the VOUT PD(MAX) = [TJ – TA]/ΘJA where TJ is the junction
pin, and connected directly between VOUT and GND temperature, TA is the ambient temperature, and
pins. The minimum value is 2.2µF but may be ΘJA is around 250°C/W for SE5166. SE5166 is

designed to enter thermal protection at 150°C. For
example, if TA is 25°C then the maximum PD is
limited to about 0.5W. In other words, if IOUT(MAX)
150mA, then [VIN – VOUT] cannot exceed 3.33V.
