TS2951
Taiwan Semiconductor
150mA Ultra Low Dropout Voltage Regulator
DESCRIPTION
The TS2951 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 TS2951 is features very low quiescent current
(75µA Typ.) and very low drop output voltage (Typ.
40µV at light load and 380mV at 100mA). 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 TS2951
useful as a low-power voltage reference.
TS2951 have other key additional feature. 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 & 3.0 of
programmed from 1.24V to 29V with external pair of
resistors. Using of as design, processing and testing
techniques make TS2951 superior over similar
products.
