SBVS026C – JULY 2001  
DMOS  
100mA Low-Dropout Regulator  
DESCRIPTION  
FEATURES  
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.  
● 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:  
Typical ground pin current is only 500µA (at IOUT = 100mA)  
and drops to 10nA when not in enabled mode. Unlike regula-  
tors with PNP pass devices, quiescent current remains rela-  
tively constant over load variation and under dropout condi-  
tions.  
IGND = 500µA at IOUT = 100mA  
Not Enabled: IGND = 10nA  
● 2.5V, 2.8V, 2.85V, 3.0V, 3.3V, 5.0V, AND  
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 main-  
tained over temperature, line, and load variations. Key  
parameters are tested over the specified temperature range  
(–40°C to +85°C).  
ADJUSTABLE OUTPUT VERSIONS  
● OTHER OUTPUT VOLTAGES AVAILABLE UPON  
REQUEST  
● FOLDBACK CURRENT LIMIT  
● THERMAL PROTECTION  
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.  
● SMALL SURFACE-MOUNT PACKAGES:  
SOT23-5 and SO-8  
APPLICATIONS  
● PORTABLE COMMUNICATION DEVICES  
● BATTERY-POWERED EQUIPMENT  
● PERSONAL DIGITAL ASSISTANTS  
● MODEMS  
● BAR-CODE SCANNERS  
● BACKUP POWER SUPPLIES
