description
The LP2950 and LP2951 are low power voltage regulators. These
devices are an excellent choice for use in battery-powered applications
such as cordless telephones, radio control systems, and portable com-
puters. The LP2950 and LP2951 feature low quiescent current and
low dropout voltage (typ. 50mV at light load and 380 mV at 100mA).
This includes a tight initial tolerance of 0.5% (typ.), extremely good
load and line regulation (0.05% typ.), and very low output temperature
coefficient, making the LP2950/LP2951 useful as a low-power voltage
reference.
The error flag output feature is used as a power-on reset for warning
of a low output voltage, due to a falling input voltage. The logic-com-
patible shutdown feature enables the regulator to be switched ON and
OFF. The LP2950 is offered in a 3-pin TO-92 package compatible with
other 5V, 3.0V & 3.3V regulators. The LP2951 is available in an 8-lead
SOIC package.
