DESCRIPTION
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.

FEATURES
*NEW DMOS TOPOLOGY:
-Ultra Low Dropout Voltage:
-230mV typ at 1A and 3.3V Output
-Output Capacitor NOT Required for Stability
*FAST TRANSIENT RESPONSE
*VERY LOW NOISE: 33μVRMS
*HIGH ACCURACY: ±2% max

DESCRIPTION
The OPA2680 represents a major step forward in unity gain stable, voltage feedback op amps.
A new internal architecture provides slew rate and full power bandwidth previously found only in wideband current feedback op amps.
A new output stage architecture delivers high currents with a minimal headroom requirement.
These combine to give exceptional single supply operation.
Using a single +5V supply, the OPA2680 can deliver a 1V to 4V output swing with over 100mA drive current and 150MHz bandwidth.
This combination of features makes the OPA2680 an ideal RGB line driver or single supply ADC input driver.
The OPA2680’s low 6.4mA/ch. supply current is precisely trimmed at 25°C.
This trim, along with low temperature drift, guarantees lower maximum supply current
than competing products.
System power may be reduced further using the optional disable control pin (SO-14 package only).
Leaving this disable pin open, or holding it high, will operate the OPA2680N normally.
If pulled low, the OPA2680N supply current drops to less than 600mA while the output goes into a high impedance state.

FEATURES
*WIDEBAND +5V OPERATION: 220MHz (G = 2)
*HIGH OUTPUT CURRENT: 150mA
*OUTPUT VOLTAGE SWING: ±4.0V
*HIGH SLEW RATE: 1800V/ms
*LOW SUPPLY CURRENT: 6.4mA/Ch.
*LOW DISABLED CURRENT: 300mA/Ch.
*ENABLE/DISABLE TIME: 25ns/100ns

APPLICATIONS
*VIDEO LINE DRIVING
*xDS*LINE DRIVER/RECEIVER
*HIGH SPEED IMAGING CHANNELS
*ADC BUFFERS
*PORTABLE INSTRUMENTS
*TRANSIMPEDANCE AMPLIFIERS
*ACTIVE FILTERS
