December 8, 2006 - Operating from 2.4-5 V of supply voltage, Model STLM20 analog-output temperature sensor offers temperature-to-voltage accuracy of 1.5C at 25C and 2.5C over -55 to 130C range. Units are supplied in 1.0 x 1.3 x 0.5 mm 4-lead UDFN and in 5-lead SOT323 packages, drawing maximum of 8 A over full temperature range. Product is suited for monitoring transmitter power amplifiers, TCSOs, and battery chargers.

Press release date: October 21, 2006

Geneva, November 21,2006 - STMicroelectronics (NYSE: STM) today announced a precision temperature sensor with an ultra-low supply current requirement of less than 4.3-microamps (typical) and a tiny 4-lead UDFN package, making it ideal for 3G cell phones and other battery applications where low power, coupled with small size, accuracy and linearity over the full temperature range, are essential. The new STLM20 is the lowest-current drop-in replacement for industry-standard LM20 devices, and is the first in a new series of precision temperature sensors from ST.

The new device is an analog-output temperature sensor operating over a -55 to +130 degrees C temperature range. At 25 degrees C the precision sensor's temperature-to-voltage accuracy is plus or minus 1.5 degrees C, and it is plus/minus 2.5 degrees C over the entire operating temperature range. The STLM20 is supplied in a tiny 1.0mm x 1.3mm x 0.5mm thick 4-lead UDFN package - as well as in 5-lead SOT323 (SC70) - to meet the demands of space constrained products.

Operating from a supply voltage of 2.4V to 5V, the STLM20 draws a maximum of 8A over the full temperature range. It is targeted for the RF section of 3G mobile phones and multimedia PDAs, monitoring transmitter power amplifiers to guarantee linearity as required by the W-CDMA (Wideband Code Division Multiple Access) 3G standards. The STLM20 is also suitable for temperature-compensated crystal oscillators and battery chargers and other portable applications, such as GPS devices and medical instruments.

The STLM20 is available now, priced at $0.25 in high volumes. For more information, go to
