SPX2946S

The SPX2945 is a low power voltage regulator. This device is an excellent choice for use in battery-powered applications such as cordless telephones, radio control systems, and portable computers. The SPX2945 features very low quiescent current (100A Typ.) and very low dropout voltage. This includes a tight initial tolerance of 1% max and very low output temperature coefficient, making the SPX2945 useful as a lowpower voltage reference.

Features of the SPX2946S are:(1)Output 3.3V, 5.0V at 400mA Output; (2)Very Low Quiescent Current, 100A; (3)Low Dropout Voltage, 420mV at 400mA; (4)Extremely Tight Load and Line Regulation; (5)Very Low Temperature Coefficient; (6)Current & Thermal Limiting; (7)Error Flag Warns Of Output Dropout; (8)Logic-Controlled Electronic Shutdown; (9)Output Programmable From 1.24V to 20V (for SO-8).

The absolute maximum ratings of the SPX2946S can be summarized as:(1)Feedback Input Voltage: -1.5V to +26V; (2)Shutdown Input Voltage:-0.3V to +26V; (3)Error Comparator Output:-0.3V to +26V; (4)ESD Rating :2kV Min; (5)Power Dissipation :Internally Limited; (6)Lead Temp. (Soldering, 5 Seconds) :260°C; (7)Storage Temperature Range:-65°C to +150°C; (8)Operating Junction Temperature Range : -40°C to +125°C; (9)Input Supply Voltage :-20V to +26V.If you want to know more information such as the electrical characteristics about the BF904, please download the datasheet in www.seekic.com or www.chinaicmart.com.
