CMOS IC

150mA LOW-DROPOUT LINEAR

REGULATORS

DESCRIPTION

The UTC L1913 is a low supply current, low dropout linear

regulator. It is operating at 2.5V - 5.5V. The supply current is as low

as 55μA in the no–load condition. In the shutdown mode, the

maximum supply current is less than 1μA.

A built-in over-temperature protection circuit is designed to protect

the device from being damaged by thermal overload. The

over-current protection limit is set at 250mA (TYP.) and 150mA

(MIN.).

The UTC L1913 can be operated on the following two modes.

When the SET pin is connected to ground, the output of L1913 is a

pre-set value and the external components are not needed to decide

the output voltage. When an output other than the preset value is

needed, two external resistors should be used as voltage dividers

and then the output voltage is decided by the resistor ratio.

The UTC L1913 is generally used in notebook computers, cellular

phones, PDAs, digital still camera and video recorders and other

hand-held devices.
