REG104GA-5

The REG104GA-5 is a 5V fixed output low-noise low-dropout (LDO) Linear Regulator with low ground pin current. Its new DMOS topology provides significant improvement over previous designs, including low-dropout (LDO) voltage and better transient performance. In addition, no output capacitor is required for stability, unlike conventional low-dropout (LDO) 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. 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.
