Description
The SE5169 series of fixed output low dropout
linear regulators are designed for portable battery
powered applications, which require low power
consumption and low dropout voltage.
Each
device contains a bandgap voltage reference, an
error amplifier, a PMOS power transistor, and
resistors for setting output voltage, and current limit
and temperature limit protection circuits.
The SE5169 has been designed to be used
with low cost capacitors and requires a minimum
output capacitor of 1.0μF. The output voltages
range from 1.3V to 4.4V in 100mV increments.
Standard voltage versions are 1.5, 1.8, 2.5, 2.8, 3.0,
and 3.3V.
Features
Typical 110mV Dropout Voltage at 150mA.
Excellent Line and Load Regulation.
High Accuracy Output Voltage of 2%.
Ultra-Low Ground Current at 35μA (Typ.)
Over Current and thermal Protection.
No Reverse Current.
Available in SOT-23-3L and TO-92 Packages
100% Lead (Pb)-Free
Application
USB removable devices
MPEG4 devices
Wireless LAN’s
Hand-Held Instrumentation.
Portable DVD players

Marking Information
Starting with 1, a bar on top of 1 is
for production year 2001, and
underlined 1 is for year 2002.
The
next character is marked on top for
2003, and underlined for 2004. The
naming pattern continues with
consecutive characters for later
years.
The last character is the week
code. (
A-Z:
1-26, a-z: 27-52)
A dot on top right corner is for
lead-free process.
LF: lead free.
