General Description
The TS2950/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 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 useful as a low-
power voltage reference.
Features
● Extremely low quiescent current
● Low dropout voltage
● Extremely tight load and line regulation
● Very low temperature coefficient
● Need only 1uF for stability
● Use as Regulator or Reference
● Stable with low-ESR output capacitors
● Current and thermal limiting
Application
● Battery powered systems
● SMPS Post-Regulator
● Voltage Reference
● Portable consumer equipment
● Radio control system

Note 1: Output voltage temperature coefficients defined as the worst case voltage change divided by the total
temperature range.
Note 2: Unless otherwise specified all limits guaranteed for Tj= 25oC, Vin= 6V, IL= 100uA and CL= 100uF.
Note 3: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle.
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.
