DESCRIPTION

The REG101 is a family of low-noise, low-dropout linear regulators with low ground pin current. Its new DMOS topology provides significant improvement over previous designs, including low dropout voltage (only 60mV typ at full load), and better transient performance. In addition, no output capacitor is required for stability, unlike conventional low-dropout regulators that are difficult to compensate and require expensive low ESR capacitors greater than 1µF. Typical ground pin current is only 500µA (at I OUT = 100mA) and drops to 10nA when not in enabled mode. Unlike regula- tors with PNP pass devices, quiescent current remains rela- tively constant over load variation and under dropout condi- tions. The REG101 has very low output noise (typically 23µVrms for V OUT = 3.3V with CNR = 0.01µF), making it ideal for use in portable communications equipment. Accuracy is main- tained over temperature, line, and load variations. Key parameters are tested over the specified temperature range (–40°C to +85°C). The REG101 is well protected—internal circuitry provides a current limit that protects the load from damage. Thermal protection circuitry keeps the chip from being damaged by excessive temperature. The REG101 is available in the SOT23-5 and the SO-8 packages. REG101 (Fixed Voltage Versions) Enable Gnd 0.1µF C OUT (1)++ VOUTVIN NR NR = Noise Reduction NOTE: (1) Optional.

ABSOLUTE MAXIMUM RATINGS (1) Operating Temperature Range (T NOTE: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. Texas Instru- ments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degrada- tion to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

However, transient response can be improved with proper capacitor selection. (2) Dropout voltage is defined as the input voltage minus the output voltage that produces a 2% change in the output voltage from the value at VIN = VOUT + 1V at fixed load. (3) Current limit is the output current that produces a 10% change in output voltage from VIN = VOUT + 1V and IOUT = 2mA. (4) For VENABLE > 6.5V, see typical characteristic “IENABLE vs VENABLE ”. (5) The REG101 no longer regulates when VIN < VOUT + VDROP (MAX) . In drop-out, the impedance from VIN to VOUT is typically less than 1Ω at TJ = +25°C.

Pb-Free (RoHS Exempt):This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br):TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
