SBVS024E – NOVEMBER 2000 – REVISED MARCH 2003  
DMOS  
250mA Low-Dropout Regulator  
DESCRIPTION  
FEATURES  
The REG102 is a family of low-noise, low-dropout linear  
regulators with low ground pin current. The new DMOS  
topology provides significant improvement over previous  
designs, including low-dropout voltage (only 150mV 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:  
150mV typ at 250mA  
Output Capacitor not Required for Stability  
● FAST TRANSIENT RESPONSE  
●
VERY LOW NOISE: 28µVrms  
● HIGH ACCURACY: ±1.5% max  
● HIGH EFFICIENCY:  
Typical ground pin current is only 600µA (at IOUT = 250mA)  
and drops to 10nA when not enabled. Unlike regulators with  
PNP pass devices, quiescent current remains relatively con-  
stant over load variations and under dropout conditions.  
IGND = 600µA at IOUT = 250mA  
Not Enabled: IGND = 0.01µA  
● 2.5V, 2.8V, 2.85V, 3.0V, 3.3V, AND 5.0V  
ADJUSTABLE OUTPUT VERSIONS  
The REG102 has very low output noise (typically 28µVrms  
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 main-  
tained over temperature, line, and load variations. Key pa-  
rameters are tested over the specified temperature range  
(–40°C to +85°C).  
● OTHER OUTPUT VOLTAGES AVAILABLE UPON  
REQUEST  
● FOLDBACK CURRENT LIMIT  
● THERMAL PROTECTION  
● SMALL SURFACE-MOUNT PACKAGES:  
SOT23-5, SOT223-5, and SO-8  
The REG102 is well protected—internal circuitry provides a  
current limit that protects the load from damage; furthermore,  
thermal protection circuitry keeps the chip from being dam-  
aged by excessive temperature. The REG102 is available in  
SOT23-5, SOT223-5, and SO-8 packages.  
APPLICATIONS  
● PORTABLE COMMUNICATION DEVICES  
● BATTERY-POWERED EQUIPMENT  
● PERSONAL DIGITAL ASSISTANTS  
● MODEMS  
● BAR-CODE SCANNERS  
● BACKUP POWER SUPPLIES
