150mA Low Dropout  
Voltage Regulators  
CORPORATION  
CLM2950 / CLM2951  
FEATURES  
PRODUCT DESCRIPTION  
5V, 3.3V, and 3.0V Versions at 150mA Output  
Very Low Quiescent Current  
Low Dropout Voltage  
Extremely Tight Load and Line Regulation  
Very Low Temperature Coefficient  
Needs Only 1µF for Stability  
Current and Thermal Limiting  
Unregulated DC Input can Withstand -20V Reverse  
Calogic’s CLM2950 and CLM2951 are low power voltage  
regulators. These devices are an excellent choice for use in  
battery-powered applications such as cordless telephones,  
radio control systems, and portable computers. The CLM2950  
and CLM2951 features very low quiescent current and very  
low dropout voltage (Typ. 50mV at light load and 380mV at  
100mA). This includes a tight initial tolerance of 0.5% typ.,  
extremely good load and line regulation of 0.05% typ. and  
very low output temperature coefficient, making the  
CLM2950/CLM2951 useful as a low-power voltage reference.  
Other key additional features of this device includes higher  
output current (150mA), positive transient protection up to 60V  
(Load dump), and the ability to survive an unregulated input  
voltage transient of -20V below ground (reverse battery).

CLM2951 Versions Only  
Error Flag Warns of Output Dropout  
Logic-Controlled Electronic Shutdown  
Output Programmable from 1.24 to 29V  
•
•
The error flag output feature is used as power-on reset for  
warning of a low output voltage, due to falling voltage input of  
batteries. Another feature is the logic-compatible shutdown  
input which enables the regulator to be switched on and off.  
The CLM2950 is offered in a 3-pin TO-92 package compatible  
with other 5 volt regulators. The CLM2951 is also available in  
8-pin plastic and SO-8.
