REG113  
SBVS031D – MARCH 2001 – REVISED SEPTEMBER 2005  
DMOS  
400mA Low-Dropout Regulator  
DESCRIPTION  
FEATURES  
The REG113 is a family of low-noise, low-dropout linear  
regulators with low ground pin current. Its new DMOS topol-  
ogy provides significant improvement over previous designs,  
including low-dropout voltage (only 250mV 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 re-  
quire expensive low ESR capacitors greater than 1µF.  
● CAP-FREE DMOS TOPOLOGY:  
Ultra Low Dropout Voltage:  
250mV typ at 400mA  
Output Capacitor not Required for Stability  
● UP TO 500mA PEAK, TYPICAL  
● FAST TRANSIENT RESPONSE  
●
VERY LOW NOISE: 28µVrms  
● HIGH ACCURACY: ±1.5% max  
● HIGH EFFICIENCY:  
Typical ground pin current is only 850µA (at IOUT = 400mA)  
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 = 850µA at IOUT = 400mA  
Not Enabled: IGND = 0.01µA  
The REG113 has very low output noise (typically 28µVrms  
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).  
● 2.5V, 2.85V, 3.0V, 3.3V, AND 5.0V OUTPUT VERSIONS  
● OTHER OUTPUT VOLTAGES AVAILABLE UPON  
REQUEST  
● FOLDBACK CURRENT LIMIT  
● THERMAL PROTECTION  
● SMALL SURFACE-MOUNT PACKAGES:  
SOT23-5 and MSOP-8  
The REG113 is well protected—internal circuitry provides a  
current limit which protects the load from damage, further-  
more, thermal protection circuitry keeps the chip from being  
damaged by excessive temperature. The REG113 is avail-  
able in SOT23-5 and MSOP-8 packages.  
APPLICATIONS  
● PORTABLE COMMUNICATION DEVICES  
● BATTERY-POWERED EQUIPMENT  
● PERSONAL DIGITAL ASSISTANTS
