General Description
The TS2950/A & TS2951/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 1% (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.
TS2950/A & 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 & TS2951/A superior over
similar products.
