EHP878L
Description
The EHP878L three terminal positive regulator is available with 3.3V or 5V fixed output voltage, making it useful in a wide range of applications. Used as a Zener-diode and resistor bination replacement, the EHP878L usually provides an effective output impedance improvement of two orders of magnitude and lower quiescent current. These regulators can provide local, on-card regulation, eliminating distribution problems associated with single-point regulation. The available voltages allow the EHP878L to be used in logic systems, instrumentation and other solid-state electronic equipment.
The EHP878L is available in TO-92 package, SOT-23-3 package, SOT-89-3 package, and SOP-8 package. With adequate heat sinking, the regulator can deliver 100m A output current. Current limiting is included to limit the peak output current to a safe value. Safe area protection for the output transistors is provided to limit internal power dissipation. If internal power dissipation is too high for...
