LP2950ACZ-3.3 100mA 3.3V Voltage Reg IC
The LP2950 and LP2951 are micropower voltage regulators that are
specifically designed to maintain proper regulation with an extremely
low input to output voltage differential. These devices feature a very
low quiescent bias current of 75 A and are capable of supplying
output currents in excess of 100 mA. Internal current and thermal
limiting protection is provided.
The LP2951 has three additional features. The first is the Error
Output that can be used to signal external circuitry of an out of
regulation condition, or as a microprocessor power on reset. The
second feature allows the output voltage to be preset to 5.0 V, 3.3 V or
3.0 V output (depending on the version) or programmed from 1.25 V
to 29 V. It consists of a pinned out resistor divider along with direct
Shutdown input that allows a logic level signal to turn off or turn on
Due to the low input to output voltage differential and bias current
specifications, these devices are ideally suited for battery powered
computer, consumer, and industrial equipment where an extension of
useful battery life is desirable. The LP2950 is available in the three
pin case 29 and DPAK packages, and the LP2951 is available in the
eight pin dual in line, SOIC 8 and Micro8 surface mount packages.
The A suffix devices feature an initial output voltage tolerance
