G958
800mA Adjustable Low-Dropout Linear Regulator
Features
General Description
The G958 is a low dropout linear regulator with a
dropout of 1.2V at 500mA of load current. It is
available in an adjustable version, which can set
the output from 1.25V to 5V with only two external
resistors.
Available in Adjust Version
Space Saving SOT-89 Package
Internal Short Circuit Current Limiting
Internal Over Temperature Protection
Current limit in Excess of 800mA
The G958 provides over temperature and over
current protection circuits to prevent it from being
damaged by abnormal operating conditions.
Applications
Post Regulation for Switching DC/DC Con-
verter
The G958 is available in SOT-89 packages. A
minimum of 10µF tantalum electrolytic capacitor is
required at the output to improve the transient
response and stability.
