Features
SE5166
Description
The SE5166 series of fixed output low dropout
linear regulators are designed for portable battery
powered applications, which require low dropout
voltage and low ground current.
Each device
contains a voltage reference unit, an error amplifier,
a PMOS power transistor, and resistors for setting
output voltage, and current limit and temperature
limit protection circuits.
The SE5166 has been designed to be used
with low cost capacitors and requires a minimum
output capacitor of 1.0µF. Standard voltage versions
are 1.5, 1.8, 2.5, 2.8, 3.0, and 3.3V.
Typical Low Dropout Voltage of 203mV at
75mA.
Guaranteed 150mA output over the full
operating temperature range.
Excellent Line and Load Regulation.
High Accuracy Output Voltage of 2%.
Typical Low Ground Current at 1mA
Current Limiting and Thermal Protection.
Standard SOT-23-3L, TO-92, and SOT-323-3L
Package.
Applications
Cellphones.
Wireless LAN’s.
Hand-Held Instrumentation.
Portable Video Game Devices.
Digital Cameras.
