Ordering Information
G9191
General Description
The G9191 is a low supply current, low dropout linear
regulator that comes in a space saving SOT-23-5
package. The supply current at no-load is 100µA. In
the shutdown mode, the maximum supply current is
less than 1µA. The over-current protection limit is set
at 430mA typical. An overtemperature protection circuit is built-in in the G9191 to prevent thermal overload.
These power saving features make the G9191 ideal
for use in the battery-powered applications such as
notebook computers, cellular phones, and PDA’s.
These devices feature a shutdown function and are
offered in active low with auto discharge. The G9191
is specifically designed to employ ceramic output capacitors.
