PJ2950/PJ2951

150mA Low Dropout Voltage Regulators

he Semiconductor PJ2950 and PJ2951 are a low power

voltage regulators. These devices are excellent choi ce

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.

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 (75μA Typ.) and very low drop output voltage

(Typ. 40μV 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 coefficient, 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 regulator output voltage may be pin-strapped for a

5 & 3.3 volt of programmed from 1.24 volt to 29 volts with

external pair of resistors. Using of as design, processing and

testing techniques make our PJ2950 and PJ2951 superior

over similar products.
