General Description
The G9052 is a dual, low supply current, low dropout
linear regulator that comes in a space saving
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 over-temperature pro-
tection circuit is built-in in the G9052 to prevent ther-
mal overload. These power saving features make the
G9052 ideal for use in the battery-powered applica-
tions such as notebook computers, cellular phones,
and PDA’s.
The G9052 have two logic inputs that select one of
nine preset output-voltage combinations, eliminating
external 1% resistors. The G9052 configures output
voltages at VOUT1 and VOUT2 based on the state of
P1 and P2 at power-on. Subsequent changes to P1
and P2 do not change the output voltages unless the
supply power is cycled, or all EN inputs are simulta-
neously driven low to shut down the device. These
devices feature a shutdown function and are offered in
active low with auto discharge. The G9052 comes in a
space saving TDFN2X2-8 package.
