First, And this is important.
I have been selling for over 20 years and have no Negative (or even Neutral) reviews. ALWAYS POSITIVE. Any Item may be returned within 30 days of delivery (except international purchases). If it's dead, send it back for a refund, you have NO risk.
These are brand new, never mounted or powered.
The LP396x series of fast ultra-low-dropout linear regulators operate from a 2.5-V to 7-V input supply. A wide range of preset output voltage options are available. These ultra-low dropout linear regulators respond very fast to step changes in load which makes them suitable for low-voltage microprocessor applications. The LP3961 and LP3964 are developed on a CMOS process which allows low quiescent current operation independent of output load current, as well as operation under extremely low dropout conditions.
Dropout Voltage: Ultra-low dropout voltage; typically 24 mV at 80-mA load current and 240 mV at 800-mA load current.
Ground Pin Current: Typically 4 mA at 800-mA load current.
ERROR Flag: ERROR flag goes low when the output voltage drops 10% below nominal value (for LP3961).
SENSE: SENSE pin improves regulation at remote loads (for LP3964).
Precision Output Voltage: Multiple output voltage options are available ranging from 1.2 V to 5 V and adjustable (LP3964), with a specified accuracy of ±1.5% at room temperature, and ±3% over all conditions (varying line, load, and temperature).
