This release in:

MALVERN, PENNSYLVANIA — Oct. 8, 2008 — Vishay Intertechnology, Inc. (NYSE: VSH) today extended its LDO product family portfolio with the release of the new SiP21110 250-mA LDO voltage regulator. The cost-effective device features a low 35-μA typical ground current at a 1-mA load in the space-saving Thin SOT23-5L package.

The SiP21110’s ultra-low ground current helps to extend battery run times between charges in battery-operated power systems and portable electronics, such as cell phones and wireless handsets, PDAs, digital cameras, pagers, wireless modems, and medical handheld devices.

The SiP21110 features adjustable output from 1.3 V to 5 V with an external resistor network, and a high 1.0 % output voltage accuracy at +25 C. Its advanced design architecture allows stable operation with very small, low-ESR ceramic output capacitors, reducing board space and component cost. Additional SiP21110 features include excellent transient response, low peak-to-peak transient output voltage with fast recovery time, as well as high PSRR, while consuming a minimum of current.

The device is designed to maintain regulation while delivering 330-mA typical peak current for systems with a high surge current upon turn-on. During start-up, an active pull-down circuit improves the output transient response and regulation. In shutdown mode, the output automatically discharges by connecting the output to ground through a 100-Ω n-channel MOSFET.

For safe operation, the device offers thermal overload (+160 C typical) and built-in short circuit protection (500 mA typical), with a 1-μA maximum shutdown current at +85 C. The SiP21110 operates over a junction temperature range of −40 C to +125 C.

Samples and production quantities of the new SiP21110 LDO voltage regulator are available now, with lead times of eight weeks for larger orders.
