PJ2951

The Semiconductor PJ2950 and PJ2951 are a low power voltage regulators. These devices are excellent choi ce for use in battery-powered applications such as cordless telephone, radio control systems, and portable computers.

The PJ2950 and PJ2951 features very low quiescent current (75A Typ.) and very low drop output voltage (Typ. 40V at light load and 380 mV at 100 mA).This includes a tight initial tolerance of 0.5% typ., extremely good load and line regulation 0.05% typ. and very low output temperature coeffi cient, making the PJ2950/PJ2951 useful as a low-power voltage reference. Other key additional feature of this unregulated input voltage transient of -20V below ground (reverse battery).

The error flag output feature is used as power-on reset for warn of a low output voltage , due to following batteries on input. Other feature is the logic-compatible shutdown input which enable the regulator to be switched on and off. The PJ2950 is offered in 3-pin TO-92 package compatible with other 5 volt regulators. The PJ2951 is available in 8-pin plastic, SOP-8 package.

The regulator output voltage may be pin-strapped for a 5 & 3.3 volt of programmed from 1.24 volt to 29 volts with external pai r of resistors. Using of as design, processing and testing techniques make our PJ2950 and PJ2951 superior over similar products.
