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.
