300mA Low-Dropout Linear Regulators
Features
General Description
„
The G9131 is a low supply current, low dropout linear
regulator that comes in a space saving SOT-23 package. The supply current at no-load is 90µA. An over
temperature protection circuit is built-in in the G9131
to prevent thermal overload. These power saving features make the G9131 ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s.
