SGM2039  
Fast Transient Response,  
1A, Low Noise, Low Voltage,  
Low Dropout Linear Regulator  
GENERAL DESCRIPTION  
FEATURES  
The SGM2039 is a low noise, low voltage, fast transient  
response and low dropout voltage linear regulator  
which is based on CMOS technology and it provides 1A  
output current capability. The operating input voltage  
range is from 1.8V to 5.5V. The fixed output voltage  
range is from 0.8V to 4.2V and adjustable output  
voltage range is from 0.8V to 5.0V.  
● Operating Input Voltage Range: 1.8V to 5.5V  
● Fixed Outputs of 0.8V, 0.9V, 1.0V, 1.05V, 1.1V, 1.2V,  
1.8V, 2.5V, 2.8V, 3.0V, 3.3V and 4.2V  
● Adjustable Output from 0.8V to 5.0V  
● Quiescent Current: 55μA (TYP)  
● Low Dropout Voltage:  
88mV (TYP) at 1A, VOUT = 3.3V  
● EN Pull-Down Current: 120nA (TYP)  
Other features include logic-controlled shutdown mode,  
short-circuit current limit and thermal shutdown  
protection. The SGM2039A has automatic discharge  
function to quickly discharge VOUT in the disabled status.  
● Current Limiting and Thermal Protection  
● Excellent Load and Line Transient Responses  
● Stable with Small Case Size Ceramic Capacitors  
● SGM2039A: With Output Automatic Discharge  
● SGM2039B: Without Output Automatic Discharge  
● -40℃ to +125℃ Operating Temperature Range  
● Available in a Green XTDFN-1.6×1.2-8L Package  
The SGM2039 is suitable for various applications which  
need low noise and fast transient response power  
supply, such as power supply of camera module in  
smart phones. Fixed or adjustable output voltage  
versions are provided.  
APPLICATIONS  
The SGM2039 is available in a Green XTDFN-1.6×1.2-8L  
package. It operates over an operating temperature  
range of -40℃ to +125℃.
