Product overview
Overview
PRODUCT
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 computers.
The LP2950 and LP2951 features low quiescent current and very 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.
