Single Output LDO, 100mA, Fixed(2.85V), Low Noise, Fast Transient Response

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 1F.
Typical ground pin current is only 500A (at IOUT = 100mA) and drops to 10nA when not in enabled mode. Unlike Regulators with PNP pass devices, quiescent current remains relatively constant over load variation and under dropout conditions.
The REG101 has very low output noise (typically 23Vrms for VOUT = 3.3V with CNR = 0.01F), making it ideal for use in portable Communications equipment. Accuracy is maintained over temperature, line, and load variations. Key parameters are guaranteed over the specified temperature range (-40C to +85C).
The REG101 is well protected?internal circuitry provides a current limit which 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.
