TS2950 150mA Ultra Low Dropout Voltage Regulator TO-92 Pin Definition: 1. Output 2. Ground 3. Input General Description The TS2950 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 is features very low quiescent current (75A Typ.) and very low drop output voltage (Typ. 40mV at light load and 380mV at 100mA), extremely good load and line regulation 0.05% typ. and very low output temperature coefficient, making the TS2950 useful as a low-power voltage reference.

Changes in output voltage due to heating effects are covered under the specification for thermal regulation. Note 4: line regulation is guaranteed by design to 0.2%. Note 5: Dropout Voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured at 1V differential at very low value of programmed output voltage, the minimum input supply voltage of 2V (2.3V over temperature) must be taken in to account. 2/10 Version: F14
