1 / 9 page  TS2951 Taiwan Semiconductor Document Number: DS_P0000207 1 Version: G15 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. FEATURES ● Output voltage available in 5V, 3V & 3.3V ● Extremely low quiescent current ● Low dropout voltage ● Extremely tight load and line regulation ● Very low temperature coefficient ● Need only 1µF for stability ● Use as Regulator or Reference ● Stable with low-ESR output capacitors ● Current and thermal limiting ● Error Flag warns of output dropout ● Logic-Controlled electronic shutdown ● Additional voltage tap ● Output voltage sense ● Output programmable from 1.24 to 29V APPLICATION ● Battery powered systems ● SMPS Post-Regulator and Voltage Reference ● Voltage Reference ● Portable consumer equipment SOP-8 Pin Definition: 1. Output 2. Sense 3. Shutdown 4. Ground 5. Error flag 6. Voltage tap 7. FB 8. Input Notes: Moisture sensitivity level: level 3. Per J-STD-020 TYPICAL APPLICATION CIRCUIT Adjustable Regulator |
