G9091
300mA Low-Dropout Linear Regulators
Features
General Description
Low, 100µA No-Load Supply Current
The G9091 is a low supply current, low dropout linear
regulator that comes in a space saving SOT-23-5,
TSOT-23-5, SC-70-4(SC-82), SC-70-5, TDFN2X2-6 and
TDFN2X2-8 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 pro-
tection circuit is built-in in the G9091 to prevent ther-
mal overload. These power saving features make the
G9091 ideal for use in the battery-powered applica-
tions such as notebook computers, cellular phones,
and PDA’s.
Guaranteed 300mA Output Current
Dropout Voltage is 100mV @ 100mA Load
Over-Temperature Protection and Short-Circuit
Protection
Max. Supply Current in Shutdown Mode < 1µA
Stable with Low Cost Ceramic Capacitors
Applications
Notebook Computers
Cellular Phones
PDAs
Digital still Camera and Video Recorders
Hand-Held Devices
Bar Code Scanners
These devices feature a shutdown function and are
offered in active low with auto discharge. The G9091
is specifically designed to employ ceramic output ca-
pacitors. The G9091 comes in a space saving
SOT-23-5, TSOT-23-5, SC-70-4(SC-82), SC-70-5,
TDFN2X2-6 and TDFN2X2-8 package.
