Introduction
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 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 23μVrms for VOUT = 3.3V with CNR = 0.01μF), making it ideal for use in portable communications equipment. Accuracy is maintained 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.
Features
- NEW DMOS TOPOLOGY: Ultra Low Dropout Voltage: 60mV typ at 100mA
- Output capacitor NOT required for stability
- FAST TRANSIENT RESPONSE
- VERY LOW NOISE: 23µVrms
- HIGH ACCURACY: ±1.5% max
- HIGH EFFICIENCY: IGND = 500µA at lour = 100mA; Not Enabled: IGND = 10nA
- 2.5V, 2.8V, 2.85V, 3.0V, 3.3V, 5.0V, AND ADJUSTABLE OUTPUT VERSIONS; OTHER OUTPUT VOLTAGES AVAILABLE UPON REQUEST
- FOLDBACK CURRENT LIMIT
- THERMAL PROTECTION
- SMALL SURFACE-MOUNT PACKAGES: SOT23-5 and SO-8
Applications
