Description
The SE5167 is an efficient linear voltage
regulator. It has extra low dropout voltage. At light
loads the typical dropout voltage is 15mV, at full
load the typical dropout voltage is 380mV. The
output voltage accuracy is better than 2%.
The SE5167 has low ground current at 65uA,
so it can help prolong battery life. The SE5167 is
specially designed for hand-held, battery-powered
devices.
Features
Typical 175mV dropout voltage at 150mA.
Low Ground current at 65uA. (Typ.)
Guaranteed 300mA output over the full
operating temperature range.
Extremely tight load and line regulation.
Low temperature coefficient.
Current and thermal limiting.
No-load stability.
Available in SOT-23-3L and TO-92 Packages.
Applications
CD/DVD-ROM, CD/RW
Wireless LAN card, Keyboard, Mouse

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: P
D(MAX)
= (T
J(MAX)
- T
A
)/θ
JA
. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the
regulator will go into thermal shutdown. See Table 1 and the “Thermal Considerations” 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 100μA to 300mA. 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.
Note 7:
The Cin or Cout should be chosen carefully. Please refer to the Application Hints
