The REG104 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 230mV 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 1.7mA (at IOUT = 1A) and drops to 0.5µA in not enabled mode. Unlike regulators with PNP pass devices, quiescent current remains relatively constant over load variations and under dropout conditions.
The REG104 has very low output noise (typically 33µVRMS for VOUT = 3.3V with CNR = 0.01µF), making it ideal for use in portable communications equipment. On-chip trimming results in high output voltage accuracy. Accuracy is maintained over temperature, line, and load variations. Key parameters are tested over the specified temperature range (–40°C to +85°C).
The REG104 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 REG104 is available in the DDPAK-5 and the SOT223-5.
