TS2950-51 series

General Description

The TS2950/A & TS951/A are low power voltage regulators. These devices are excellent choice for use in

battery-powered applications such as cordless telephone, radio control systems, and portable computers.

The TS2950/A & TS2951/A is features very low quiescent current (75uA Typ.) and very low drop output voltage (Typ.

40uV at light load and 380 mV at 100 mA). This includes a tight initial tolerance of 0.5% typ.(A version), extremely good

load and line regulation 0.05% typ. and very low output temperature coefficient, making the TS2950/A & TS2951/A useful

as a low-power voltage reference.

TS2951/A have other key additional feature of 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. The logic-compatible shutdown input which enable the regulator to be switched on/off. The regulator output voltage

may be pin-strapped for a 5.0, 3.3 & 3V of programmed from 1.24V to 29V with external pair of resistors. Using of as

design, processing and testing techniques make TS2950/A & TS951/A superior over similar products.

The TS2950/A is offered in 3-pin TO-92 package, The TS2951/A is available in 8-pin plastic SOP-8 package.
